The reaction of 1,1-bis(diphenylphosphino)methane with substituted o-quinones afforded the novel 6-[bis(diphenylphosphoryl)methyl]-and 6-bis(diphenyl phosphoryl)methylidene derivatives. Moreover, 1,1-bis(diphenylphosphino)methane reacts with 3,4,5,6-tetrabromo-o-benzoquinone to give only the new 6-[bis(diphenylphosphoryl)methyl] derivative. Mechanisms accounting for the formation of the new products are discussed. The antimicrobial activity of some of the newly synthesized compounds was also examined.

The reaction of 1,2-bis(diphenylphosphino)ethane with substituted o-benzo-quinones afforded new bis(6-hydroxycyclohexa-2,4-dienone) derivatives. Treatment of the same reagent with o-naphthoquinone, phenanthrenequinone, and acenaphthenequinone gave the res
