Reactions of bis(thiophosphoryl)disulfanes and bis(thiophosphinyl)disulfanes with metal species: An alternative, convenient route to metal complex and organometallic dithiophosphates and dithiophosphinates

Abstract

The reactions of bis(thiophosphoryl)disulfanes, and bis(thiophosphinyl)disulfanes, X2P(S)SSP(S)X2 (X = R, OR; R = alkyl, aryl) with metals and low valent state metal compounds are reviewed. Four types of reactions of the disulfanes are possible: (a) adduct formation with ring closure through chelation (rare); (b) metal insertion, involving homolytic clevage of the S-S bond and oxidative addition of the metal species (typical for active metals and low valent metal species); (c) redistribution between M-M and S-S bonds, involving homolytic cleavage of both S-S and M-M bonds and oxidation of the metal with the formation of M-S bonds; (d) addition of the (S)PS-SP(S) moieties to metal-metal multiple bonds. © 2002 Elsevier Science B.V.
