Abstract
A process for producing 3-methyl-1-phenylphospholene oxide by subjecting dichlorophenylphosphine and isoprene to an addition reaction and then subjecting the resulting adduct to solvolysis, wherein the addition reaction between dichlorophenylphosphine and isoprene is conducted in a solvent to obtain an adduct in the form of a slurry or solution and the slurry or solution is subjected to solvolysis. This process can easily produce 3-methyl-1-phenylphospholene oxide which is used in various reactions, and is free from the drawbacks of the conventional process.
