TL;DR: The first 3-silylated phosphol-3-enes using a modified McCormack reaction sequence was reported in this paper, where the complete protodesilylation observed in standard conditions is suppressed when the reaction between 2-Silylated 1,3-butadiene and dichlorophenylphosphine is carried out in the presence of a small amount of copper stearate in acetic anhydride at 50°C.
Abstract: We report the synthesis of the first 3-silylated phosphol-3-enes using a modified McCormack reaction sequence The complete protodesilylation observed in standard conditions is suppressed when the reaction between 2-silylated 1,3-butadiene and dichlorophenylphosphine is carried out in the presence of a small amount of copper stearate in acetic anhydride at 50°C The new phospholenes contain a reactive vinylsilane function which has been epoxidized by m-chloroperbenzoic acid The bicyclic compound has a cis structure as established by classical spectroscopic methods and corroborated by molecular modelling

TL;DR: In this article, a method for producing 3-methyl-1-phenylphospholene oxide by addition-reacting isoprene to dichlorophosphine and subsequently decomposing the resultant adduct with water or an alcohol is described.
Abstract: PURPOSE:To provide the method in which the technical difficulties in the prior art have been eliminated and which is capable of simply producing the 3- methyl-1-phenylphospholene oxide used for various reactions. CONSTITUTION:A method for producing 3-methyl-1-phenylphospholene oxide by addition-reacting isoprene to dichlorophosphine and subsequently decomposing the resultant adduct with water or an alcohol is characterized by addition- reacting the isoprene to the dichlorophenylphosphine in a solvent not having an active hydrogen and subsequently decomposing the slurry or solution of the resultant adduct with the water or alcohol.
