Abstract

The transfer of carbene ligands from transition-metal-carbene complexes to alkenes with formation of cyclopropanes represents a general class of reactions with considerable potential synthetic utility. Unfortunately, however, few of the stable, isolable carbene complexes prepared to date exhibit this mode of reactivity. l The most notable exception is the report by Casey that (C0) 5WCHC6H5 generated in situ (trifluoroacetic acid-methylene ...
