12. 3 has never been reported to catalyze chain transfer, although Gridnev and co-workers (ref 7b) have remarked that "the hydridocobalt chelate (LCoH) is an assumed but unobserved intermediate species".

30. A patent on CT catalysis by dinuclear Cp carbonyl complexes (Janowicz, A. H. U.S. Patent 4,746,713, May 24, 1988) has been brought to our attention; they are far less active than the monomeric 1 that we have employed.
