摘要：

Rh(PMe3)2(CO)Cl catalyzes the photochemical dehydrogenation of alkanes to yield alkenes. H2 is evolved or, in the presence of potential hydrogen acceptors such as t-butylethylene and styrene, hydrogen can be transferred to the olefins. The photokinetics and selectivity of the dehydrogenation reactions have been investigated. Both reactions proceed via a single photochemical step, photoextrusion of carbon monoxide from Rh(PMe3)2(CO)Cl. Study of the transfer-dehydrogenation, particularly of the product ratio (H2 : hydrogenated acceptor), reveals aspects of the dehydrogenation mechanism including steps subsequent to the turnover-limiting step. © 1990.
