Simple procedures have been developed for the synthesis of 2-chloro-5,5-dimethyl-2,5-dihydro- 1,2 lambda(5)-oxaphosphole 2-oxide by one-pot electrophilic cyclization of 3-methylbuta-1,2-dien-1-ylphosphonic dichloride and of (Z)-4-[dialkyl(diphenyl)phosphoryl]-2-methylbut-3-en-1-ol by reaction of 2-chloro-5,5-dimethyl- 2,5-dihydro-1,2 lambda(5)-oxaphosphole 2-oxide with organomagnesium compounds.
