The carbocupration reaction of alkynyl carbamates leads to the stereospecific preparation of polysubstituted alkenyl carbamates. Subsequent treatment of these enol carbamates with the Negishi reagent gave the corresponding vinyl zirconocene species.
炭基铜化反应的烷基碳酸酯导致了多取代烯基碳酸酯的立体特异性制备。随后用Negishi试剂处理这些烯醇碳酸酯,得到了相应的乙烯基锆烷基物种。
