PREPARATION OF 1,2-DIHYDRO-1,2-DIPHENYL-1λ,2λ-DIPHOSPHORIN 1,2-DISULFIDE

1,2-Dihydro-1,2-diphenyl-1λ,2λ-diphosphorin 1,2 disulfide was synthesized from the corresponding 1,2,3,6-tetrahydro derivative by lithiation, bromination with bromotrichloromethane and dehydrobromination successively.Direct bromination of 1,2,3,6-tetrahydro derivative resulted in the P-P bond cleavage.
