Abstract

A series of osmium meso -tetra-p -tolylporphyrln carbene complexes, (lTP)Os=CRR' [R, R' = p-tolyl (1); R = H, R' = SIMe3 (2), CO~t (3)], have been prepared by treating [ Os(TTP)] 2 with the appropriate dla· zoalkane (N2CRR'). The carbene complexes, 1-3, and the osmium complexes [Os(TTP)]2, Os(TTPXCOXpy), and Os(lTPXpy)2 catalytically convert ethyl dlazoacetate to dlethyl maleate and dlethyl fumarate In high yields and high stereoselectlvlty. The Z/Eratios range from 18:1 to 26:1. Olefin also can be produced from N2C(p-C8H4- CH3)2 but not from N2CHSIMe3•
