Abstract

Phenylphosphonic and phenylphosphonothioic dichlorides were dechlorinated with magnesium to generate phenylphosphinylidene and phenylphosphinothioylidene, respectively, in the presence of several 1, 3-dienes. Reactions of phenylphosphinothioylidene with 2, 3-dimethylbutadiene and 1, 3-cyclohexadiene gave Diels-Alder type reaction products, that is, 3, 6-dihydro-1, 2-thiaphosphorin derivatives (5 ...
