Formation of (σ-butatrienyl)- and (σ-enynyl)cobaloxime complexes via reaction of (dimethylglyoximato)(pyridine)cobalt anion, [Co(dmgH)2py]-, with alkynylvinyl triflates. Stereochemistry and mechanism of formation

Alkynylvinyl triflates readily react with [Co(dmgH)2py]- (4) to give either (σ-enynyl)- or (σ-butatrienyl)cobaloxime complexes depending upon the substitution pattern of the starting inflate. Reaction of either isomeric vinyl triflate 2E or 2Z gives only a single product enynyl complex 13E. In contrast reaction of isomeric vinyl triflates 3E and 3Z with 4 is stereospecific, presumably with retention of olefin geometry, giving only the respective (σ-butatrienyl)cobaloxime complexes. A double nucleophilic vinylic substitution is invoked to rationalize these results.
