Reaction of the second-generation Grubbs metathesis catalyst [RuCl 2(=CHPh)(H2IMes)(PCy3)] (2) (H2IMes = 1,3-dimethyl-4,5-dihydroimidazol-2-ylidene) with primary alcohols in the presence of a base produced the complexes [RuClH(CO)(PCy3) 2] (3) and [RuClH(CO)(H2IMes)(PCy3)] (5). When benzyl alcohol was used, the ruthenium phenyl complexes [RuClPh(CO)(PCy 3)2] (4) and [RuClPh(CO)(H2IMes)(PCy 3)] (7) were formed in addition to 3 and 5. Complex 7, characterised by an X-ray structure analysis, was also formed on exposure of 2 to oxygen. The isomerization and hydrogenation activity of 7 was determined and compared with that of 3 and 4. ( Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003).
