Mechanistic investigation of homogeneous hydrogen transfer from 1-phenylethanol to cyclohexanone catalyzed by dichlorotris(triphenylphosphine)- ruthenium(II)

Add time:09/02/2019    Source:sciencedirect.com

In the homogeneous hydrogen transfer from 1-phenyl-ethanol(D) to cyclohexanone(A) catalyzed by RuCl2(PPh3)3(C) in diphenyl ether as solvent at 140 °C the order of addition of donor, acceptor and catalyst have a pronounced effect on the rate of the reaction. An induction period is observed. The experimental observations correspond to the rate expression:Initial rate = where [C]t is the total concentration of catalyst in the system.
