Transfer-hydrogenation and Transfer-hydrogenolysis. I. Transfer-hydrogenation of Cyclooctadienes Catalyzed by Dichlorobis(triphenylphosphine)iron(II)

Abstract

Hydrogen transfer from a number of organic compounds to olefins in a homogeneous system was studied. In the case of hydrogen transfer to 1,5-cyclooctadiene, using dichlorobis(triphenylphosphine)iron(II) as the catalyst, dihydroxybenzenes, such as pyrocatechol and hydroquinone, were much superior to prim- and sec-alcohols, 1-dodecanethiol, and cyclohexene as hydrogen donors.
