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.
