Rhodium-Catalyzed Insertion Reaction of PhP Group of Pentaphenylcyclopentaphosphine with Acyclic and Cyclic Disulfides

Organophosphorus compounds with a phosphorus atom attached to a phenyl group and two organothio/organoseleno groups were synthesized using the rhodium-catalyzed insertion reaction of the PhP group of pentaphenylcyclopentaphosphine (PhP)5 with acyclic disulfides and diselenides. The method was applied to the synthesis of heterocyclic compounds containing the S-P-S group by the reaction of (PhP)5 and cyclic disulfides such as 1,2-dithietes, 1,2-dithiocane, 1,4,5-dithiopane, and 1,2-dithiolanes.

INTERACTION OF DISULFIDES AND SULFENYLCHLORIDES WITH C-N,N-DIALKYLAMINOSUBSTITUTED PHOSPHAALKENES

Interaction of dialkyl disulfides with C-N,N-dimethylaminomethylene-P-phenylphosphine 1a results in the complete cleavage of the P=C double bond and formation of S,S-dialkylphenyldithiophosphonites.Ethyl sulfenylchloride undergoes dehydrochlorination by 1a, while phenyl sulfenylchloride cleaves the P=C bond in C-N,N-dialkylaminosubstituted phosphaalkenes with the predominant formation of either PhP(SPh)2 6 or PhP(SPh)Cl 7 depending on the phosphaalkene used and reaction conditions. Key words: C-(N,N-dialkylamino) substituted phosphaalkenes; disulfides; sulfenylchlorides.

REACTION OF PHENYLSULFENYL CHLORIDE WITH C-(N,N-DIMETHYLAMINO)-METHYLENE-P-PHENYLPHOSPHINE

PhSCl adds regiospecifically to the P=C double bond in C-(N,N-dimethylamino)-methylene-P-phenylphosphine to give PhP(SPh)2 and Cl2CHNMe2.
