Abstract

Time-resolved Fourier transform infrared spectroscopy has been used to follow the time evolution of ethane and two reaction intermediates, assigned as H2Fe(CO)3(C2H4) and Fe(CO)3(C2H4)2, produced following 355-nm photolysis of gas-phase mixtures of Fe(CO)5, C2H4, and H2. The time evolution of these species indicates that both H2Fe(CO)3(C2H4) and Fe(CO)3(C2H4)2 are potential reservoirs for ethane production. The catalytic production of ethane terminates long before C2H4 and H2 are consumed. The possible role of reactions of coordinatively unsaturated intermediates with parent that may remove Fe(CO)3-containing species from the system and terminate ethane production is considered.
