-
Paragraph 0022, (2020/06/27)
PROBLEM TO BE SOLVED: To provide an efficient method for producing a tetraalkenylsilane with improved production efficiency per unit volume of a reactor. SOLUTION: Provided is a method for producing a tetraalkenylsilane represented by general formula (3), comprising reacting an alkenyl trihalosilane represented by general formula (1) (in the formula, X represents a halogen atom and n represents an integer of 0 to 16. The same holds for general formulas (2) and (3)) with a Grignard compound represented by general formula (2). SELECTED DRAWING: None COPYRIGHT: (C)2020,JPOandINPIT
Silaethenes, XV. Pyrolysis of 1-Methyl-1-vinyl-1-silacyclobutane and 1,1-Divinyl-1-silacyclobutane - Follow-up Reactions of the Silaethenes Me(Vi)Si=CH2 and Vi2Si=CH2

The pyrolysis of the silacyclobutanes Vi(Me)Si(CH2)3 (VMS) and Vi2Si(CH2)3 (V2S) at 700-800 deg C and 1E-1 - 1E-2 mbar leads to the intermediates Vi(Me)Si=CH2 and Vi2Si=CH2, which undergo isomerisation to siliranes followed by cleavage to give allene and the corresponding silylenes Me(H)Si: and Vi(H)Si: respectively.Copyrolyes of these silacyclobutanes with dienes (2,3-dimethyl-1,3-butadiene or isoprene) yield silacyclopentene derivatives (4, 14 and 20).The formation of these products supports the proposed mechanism.The simultaneous existence of silaethenes and silylenes in the gas phase is proven by the presence of the disilacyclobutanes 13 and 17, respectively, in the reaction mixtures.Using isoprene as the quenching reagent for Vi(Me)Si=CH2 the two isomeric silacyclohexenes 15 and 16 are formed in low yield, in addition to almost equal amounts of 13 and 14 (eq. (6)).
