Abstract

Mechanistic studies were conducted on reaction of [ReH4 (η2-H2)(Cyttp)] OTf (1 (OTf); Cyttp= PhP (CH2CH2CH2PCy2) 2, OTf= O3SCF3) with ketones, both neat and in solution. Treatment of 1 (OTf) with excess acetone at 60–65° C affords [ReH2 (O)(Cyttp)] OTf (2 (OTf)) in high yield, nearly 1 equiv. of H2, 2 equiv. of 2-propanol, 1 equiv. of each of 4-hydroxy-4- methyl-2-pentanone (B) and 4-methylpent-3-en-2-one (C), and smaller amounts of other ...
