The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: Trimethylphosphineoxide( cas:676-96-0 ) is researched.Synthetic Route of C3H9OP.Wang, Shichun; Heng, Yi; Li, Tongyu; Hou, Guohua; Zi, Guofu; Walter, Marc D. published the article 《Synthesis and reactivity of the uranium phosphinidene metallocene [η5-1,3-(Me3Si)2C5H3]2U(:P-2,4,6-iPr3C6H2)(OPMe3): influence of the coordinated Lewis base》 about this compound( cas:676-96-0 ) in Dalton Transactions. Keywords: reactivity uranium phosphinidene metallocene Lewis base; isothiocyanate aldehyde nitrile isonitrile azide reactivity uranium phosphinidene metallocene. Let’s learn more about this compound (cas:676-96-0).
This paper describes the synthesis and reactivity of [η5-1,3-(Me3Si)2C5H3]2U(:P-2,4,6-iPr3C6H2)(OPMe3) (6) which is accessible from a ligand exchange reaction between [η5-1,3-(Me3Si)2C5H3]2U(:P-2,4,6-iPr3C6H2)(OPPh3) (2) and Me3PO at ambient temperature Phosphinidene 6 exhibits no reactivity towards internal alkynes, but readily reacts with various hetero-unsaturated mols. such as isothiocyanates, aldehydes, nitriles, isonitriles, and organic azides, forming uranium sulfido, oxido, imido, and uranaheterocyclic compounds Nevertheless, with the bidentate ortho-dicyanobenzene o-C6H4(CN)2 the zwitterionic species [η5-1,3-(Me3Si)2C5H3]2U[NHC(N){C6H4CP(2,4,6-iPr3C6H2)CH2PMe2O}] (13) is isolated in good yield. Moreover, 6 converts with Ph2S2 to the uranium(III) phenylthiolate compound [η5-1,3-(Me3Si)2C5H3]2USPh(OPMe3) (7) in good isolated yield. Furthermore, the influence of the Lewis base on the reactivity of the uranium phosphinidene metallocenes has also been evaluated.
