Synthesis of methylenebis(diphenyl- and methylenebis(di-p-tolylphosphine) monoxides, via the reaction of diarylphosphines with formic acid in presence of concentrated hydrochloric acid is described. Methylenebis(diphenylphosphine) monoxide is oxidized with hydrogen peroxide and sulfur into the corresponding methylenebis(diphenylphosphine) dioxide and methylenebis(diphenylphosphine) monoxide monosulfide. Attempts to carry out this reaction with butylphenyl- and dibutylphosphines failed.
