Reactions of alkylidene-bridged cobaltadithiolene complexes with Lewis bases. Formation of M−S sulfur ylide structure

The reactions of a malonate (C(COOMe)2)-bridged complex with Lewis bases give novel sulfur ylide (M−S sulfur ylide) complex due to the cleavage of Co−C bond as determined by X-ray structure analysis. Acetate (CHCOOEt)- and methylene-bridged complexes, on the other hand, reacted with Lewis bases via...

Description
Summary:The reactions of a malonate (C(COOMe)2)-bridged complex with Lewis bases give novel sulfur ylide (M−S sulfur ylide) complex due to the cleavage of Co−C bond as determined by X-ray structure analysis. Acetate (CHCOOEt)- and methylene-bridged complexes, on the other hand, reacted with Lewis bases via an SN2 type reaction to give unstable M−S sulfur ylide complexes and stable six-membered-ring complexes.
