| Abstract: | The reaction of CpRu(OMe)]2 (1) with PCy3 yields the 16-electron alkoxo derivative, CpRu(OMe)(PCy3) (2). 2 reacts with H2 and HBF4 to give the known CpRuH3PCy3 (3) and CpRu(C6H9PCy2)]BF4 (4). The reaction of 1 with one or two equivalents of L yields CpRuHL2 (L = PCyPh2 (5), PCy2H (6)) through a β-elimination process. Upon protonation, 5 and 6 are converted into CpRuH2L2]BF4 (L = PCyPh2 (7), PCy2H (8)). |
