In all these experiments, characterisation of photoproducts was aided by comparison with experiments using the mononuclear fragments [(η6-C6H5C2H5)Cr(CO)3] and [(η3-C3H4C6H5)Mn(CO)4] where we were able to characterise [(η3-C3H4C6H5)Mn(CO)2], [(η6-C6H5C2H5)Cr(CO)2(N2)], [(η3-C3H4C6H5)Mn(CO)3(N2)] and [(η3-C3H4C6H5)Mn(CO)2(N2)2].

  Time-resolved infrared absorption spectroscopy is used to study the coordination reactions of N2 and H-2 with photolytically generated coordinatively unsaturated species (eta6-C6H6)Cr(CO)x and (eta5-C5H5)Mn(CO)x (x = 2 and 1) in the gas phase. Additions of N2 and H-2 to (eta6-C6H6)Cr(CO)2 and (eta5-C5H5)Mn(CO)2 form corresponding molecular nitrogen and hydrogen complexes. Additions of N2 and H-2 to (eta6-C6H6)Cr(CO) are confirmed although no product absorption is observed. By comparison, reactions of N2 and H-2 with (eta5-C5H5)Mn(CO) are not observed, presumably due to spectral overlap. The rate constants for reactions of N2 and H-2 With (eta6-C6H6)Cr(CO)2 and (eta5-C5H5)Mn(CO)2 as well as with (eta6-C6H6)Cr(CO) are measured, and an upper limit for the rate constants for reactions of N2 and H-2 with (eta5-C5H5)Mn(CO) is estimated. Significant differences are observed for the rate constants for reactions of different species and discussed with respect to spin-allowed versus disallowed processes.
