Chemical manipulation of multifunctional hydrocarbons on silicon surfaces

Over the last three decades reactions of organic and organometallic compounds on silicon surfaces have been of great interest. This interest has been fueled by potential applications of such modification approaches to form stable coatings, to improve adhesion properties of organic and inorganic films on semiconductors, and to design suitable molecular electronics components. Despite enormous amount of work on chemistry of various compounds on silicon surfaces, the major driving force behind selective assembly and molecular ordering on reactive silicon surfaces and the preference for chemical reactivity of multifunctional compounds, have never before been a subject of a comprehensive review. As more complex molecular building blocks for multiple applications become available, there is a need to understand and quantify chemical handles on how to manipulate surface reactions in such a way that highly selective processes would take place. Classical kinetics and thermodynamics approaches to surface modification will be the main focus of this review. A large number of well-developed and well-understood reactions on silicon surfaces combined with better computational approaches to describe multiple surface reaction pathways will now allow us to predict, in many cases quantitatively, the selectivity of surface reactions in a variety of experimental conditions. In the past few years numerous examples of these approaches have been published. They provide a foundation for the general understanding and prediction of the chemical properties of a variety of multifunctional compounds. Most importantly, such predictions will be further used to optimize chemical modification processes both in a research laboratory and on the industrial scale. The current review will focus on the chemical control of the selectivity in reactions of multifunctional organic and organometallic molecules on silicon substrates. After a very brief review of the potential monofunctional candidate reactions and a summary of the experimental conditions, the balance of kinetic and thermodynamic factors will be discussed and the application and prediction of surface selectivity will be outlined. The examples of selective surface modification will be further considered on the most common silicon surfaces: Si(100) and Si(111), as well as on partially hydrogenated silicon substrates. Finally, some future directions for the development and the use of multifunctional compounds on silicon will be extended into the third dimension.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 288-14-2, help many people in the next few years.Application In Synthesis of Isoxazole

Gold-Catalyzed [4 + 1]-Annulation Reactions between 1,4-Diyn-3-ols and Isoxazoles to Construct a Pyrrole Core

This work reports gold-catalyzed [4 + 1]-annulation reactions between 1,4-diyn-3-ols and isoxazoles or benzisoxazoles to yield pyrrole derivatives. The reaction chemoselectivity is controlled by an initial attack of an isoxazole at a less hindered alkyne to form gold carbenes, further inducing a 1,2-migration of a second alkyne group. A broad substrate scope of 1,4-diyn-3-ols, isoxazoles and even benzisoxazoles highlighted the reaction utility.

Easy Access to 2-Fluoro- And 2-Iodo-2 H -azirines via the Halex Reaction

A simple gram-scale method for the preparation of esters and dialkylamides of 2-(fluoro/iodo)-2 H -azirine-2-carboxylic acids via the halogen exchange (Halex) reaction of 2-bromo-substituted analogues is reported. The method operates with inexpensive and safe reagents, Bu 4 NF and potassium iodide, providing high product yields. Alternatively, 2-fluoro-2 H -azirine-2-carboxylates can be prepared from 2-iodo- and 2-chloro-analogues. The latter compounds can be obtained in practically quantitative yield by treating the 2-iodo- and 2-bromo-2 H -azirine-2-carboxylic esters with Bu 4 NCl.

Degradation of Reactive Black 5 by electrochemical oxidation

Degradation of commercial grade Reactive Black 5 (RB5) azo dye by chemical and electrochemical treatment was examined using a dimensionally stable anode and stainless steel cathodes as electrode materials, with NaCl as supporting electrolyte. The electrochemical treatment was compared to the chemical treatment with hypochlorite generated by electrolysis. The compounds present in the commercial grade RB5 azo dye and the products of its electrochemical degradation were separated using ion-pairing high performance liquid chromatography on reversed phase. The separated species were detected by diode array detector and electrospray ionization mass spectrometry. A suitable ion-pairing reversed phase HPLC-MS method with electrospray ionization for the separation and identification of the components was developed. The accurate mass of the parent and fragment ions were used in the determination of the empirical formulas of the components using the first-order mass spectra. Structural formulas of degradation products were proposed using these information and principles of organic chemistry and electrochemistry.

Chalcones and Five-Membered Heterocyclic Isosteres Bind to Alpha Synuclein Fibrils in Vitro

A series of chalcone and heterocyclic isosteres, in which the enone moiety was replaced with an isoxazole and pyrazole ring system, was synthesized and their affinities for alpha synuclein (Asyn), amyloid beta (Abeta), and tau fibrils were measured in vitro. The compounds were found to have a modest affinity and selectivity for Asyn versus Abeta fibrils and low affinity for tau fibrils. Insertion of a double bond to increase the extendable surface area resulted in an increase in affinity and improvement in selectivity for Asyn versus Abeta and tau fibrils. The results of this study indicate that compound 11 is a secondary lead compound for structure-activity relationship studies aimed at identifying a suitable compound for positron emission tomography-imaging studies of insoluble Asyn aggregates in Parkinson’s disease.

Antimicrobial activities of some newly synthesized substituted benzosuberone and its related derivatives

A series of substituted benzosuberone scaffold fused with pyrazole, isoxazole, pyrimidine and triazole moieties were synthesized and evaluated as antimicrobial agents. Some reactions were performed under microwave irradiation, resulted in short time reactions and surprisingly high yields. Some of the obtained products showed remarkable antimicrobial activities and the most active products 7b, 9, 13 and 14 were further tested to evaluate their Minimum Inhibitory Concentration (MIC) value at 125 mug/mL. The structures of new compounds were proved by their elemental analyses and spectral data.

A retrospective look at anthranilic diamide insecticides: discovery and lead optimization to chlorantraniliprole and cyantraniliprole

Anthranilic diamides are an important commercial synthetic class of insecticides (IRAC Group 28) that bind to the ryanodine receptor with selective potency against insect versus mammalian forms of the receptor. The first commercialized diamide, chlorantraniliprole, has exceptional activity against lepidopteran pests. The second anthranilamide product, cyantraniliprole, has excellent cross-spectrum activity against a range of insect orders, including both lepidopteran and hemipteran pests. Here, a retrospective look is presented on the discovery of the class, along with chemistry highlights of the lead evolution to both products.
