Abstract

Direct observation of carbonylated and dehydrogenated products from cyclohexane was conducted via in situ FTIR monitored reaction of half-sandwich iridium dicarbonyl metal centers (η⁵ pentamethylcyclopentadienyl)dicarbonyliridium and η⁵-1-(2-(dimethylamino)ethyl-2,3,4,5-tetrameth ylcyclopentadienyl)dicarbonyliridium) under CO atmosphere. Variation of pressure in semibatch experiments allows for the detection of aldehydes and alkene. Changing atmosphere from CO to compressed air resulted in ketone formation. Iridium half-sandwich complexes can be used to promote carbonylation of saturated alkanes under photoirradiation. This is an abstract of a paper presented at the AIChE Annual Meeting (Austin, TX 11/7-12/2004).
