In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Pd-Catalyzed Perfluoroalkylative Aryloxycarbonylation of Alkynes with Formates as CO Surrogates, published in 2021-06-04, which mentions a compound: 1445085-77-7, mainly applied to perfluoroalkyl unsaturated ester preparation regioselective diastereoselective DFT; acetylene perfluoroalkyl iodide formate multicomponent aryloxycarbonylation palladium catalyst, Computed Properties of C43H56NO5PPdS.
A palladium-catalyzed three-component protocol for the direct synthesis of perfluoroalkyl-substituted α,β-unsaturated esters (E)-RC(=CHR1)C(O)OR2 (R = Ph, cyclopropyl, thiophen-3-yl, hexan-1-yl, etc.; R1 = perfluorobutyl, perfluorohexyl, perfluorodecyl, perfluoroisoheptyl, 4-iodoperfluorobutan-1-yl, ; R2 = Ph, 4-fluorophenyl, 2,4,6-trichlorophenyl, etc.) from acetylenes RCC and perfluoroalkyl iodides R1I, applying formates HC(O)OR2 as convenient CO sources was reported. The tandem reaction proceeds under mild conditions with excellent regio- and stereoselectivities toward the E-isomer (>95:5, E:Z). Detailed mechanistic investigations revealed that the process proceeds through an off-cycle, base-induced decomposition of formate to CO and phenoxide, which are reassembled on the Pd-center into an aryloxycarbonyl moiety, which is ultimately installed on the alkene scaffold. To complete the mechanistic picture of the reaction, the exptl. study was supported by DFT calculations
As far as I know, this compound(1445085-77-7)Computed Properties of C43H56NO5PPdS can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
