A facile protocol for the convenient preparation of phosphino- and phosphono-containing trans-1,2-difluorovinylsilanes

Attempted preparation of phosphono containing trans-1,2-difluoro-1- phenyldimethylsilyl ethylenes R2P(O)CF = CFSiMePh 3 by deprotonation of HFC = CFSiMe2Ph 2 followed by acylation with R2P(O)Cl was unsuccessful. However, a

Fluorinated Vinylsilanes from the Copper-Catalyzed Defluorosilylation of Fluoroalkene Feedstocks

Herein, a copper-catalyzed C?F bond defluorosilylation reaction of tetrafluoroethylene and other polyfluoroalkenes is described. Mechanistic studies, based on a series of stoichiometric reactions with copper complexes, revealed that the key steps of this defluorosilylation reaction are 1) the 1,2-addition of a silylcopper intermediate to the polyfluoroalkene and 2) a subsequent selective β-fluorine elimination, which generates a Cu?F species. The β-fluorine elimination is facilitated by Lewis acidic F?Bpin, which is generated in situ during the defluorosilylation.

METHOD FOR PRODUCING SUBSTITUTED OLEFIN COMPOUND

PROBLEM TO BE SOLVED: To provide a new method for producing a substituted olefin compound, in particular, a new method for producing a fluorine-containing olefin substituted with a boron-containing group or a silicon-containing group. SOLUTION: There is provided a method for producing a compound represented by the formula (1), which comprises a step of reacting a fluorinated olefin with a compound represented by the formula (3).[R1 to R3 represent H, F, an organic group or the like; RX represents -BX2 or -SiX3; X represents H, a halogen or an organic group; provided that X may form a ring together with adjacent B or Si; Y1 and Y2 each independently represent OH or an alkoxy group; provided that Y1 and Y2 may form a ring together with adjacent B.] SELECTED DRAWING: None COPYRIGHT: (C)2017,JPO&INPIT

Low-temperature 19F NMR spectroscopy of 1-fluoro-1-lithioethenes - Stability, shifts and unexpected coupling constants

Half-lives and fluorine atom shifts of stabilized 1-fluoro-l-lithioethenes bearing hydrogen, fluorine, phenyl, and/or dimethylphenylsilyl groups in the β-positions have been determined by a low-temperature 19F NMR spectroscopy. Some 1-fluoro-1-lithioethenes displayed an exceptionally low value of the trans-3JFF coupling constant. Stereoselectivity of carbenoid formation, as well as an effect of configuration on the stability is discussed.

Process for the preparation of a trifluorovinylsilane, and fluorine-containing polymer and process for its preparation

A process for preparing a trifluorovinylsilane represented by the general formula: where each R independently represents an alkyl group, an aryl group or an aralkyl group, and n is an integer of 1 to 4, which comprises the reaction of chlorotrifluoroethyl

PRACTICAL SYNTHESIS AND POLYMERIZATION OF TRIFLUOROVINYLSILANES. A POSSIBLE PRECURSOR OF POLY(DIFLUOROACETYLENE)

An improved procedure for the preparation of trifluorovinylsilanes was established which involved addition of butyllithium to a mixture of chlorosilanes and commercially readily available chlorotrifluoroethylene at -78 to -130 deg C, and the resulting monomer was polymerized with a catalyst such as CsF or (R2N)3S(1+)*F2SiMe3(1-) to give black metallic polymer which showed conductivity of 1E-9 to 1E-10 Ω-1cm-1.
