摘要

Unprecedented rhodium-catalyzed stereoselective polymerization of “carbenes” from ethyl diazoacetate (EDA) to give high molecular mass poly (ethyl 2-ylidene-acetate) is described. The mononuclear, neutral [(N, O-ligand) MI (cod)](M= Rh, Ir) catalytic precursors for this reaction are characterized by (among others) single-crystal X-ray diffraction. These species mediate formation of a new type of polymers from EDA: carbon-chain polymers ...
