Two types of novel reactive species were generated by one-electron reductions of Fischer-type carbene complexes. In the case of tungsten complexes, one-electron reductions generated anion radical species, which added to electron-deficient olefins to give addition products. In the case of chromium complexes, carbonyl insertion occurred to give acyl chromate complexes, which underwent 1,4-addition to various electron-deficient olefins.
