react with PPh3, 5a reacts with PMe2Ph, PMePh2 and PPh3 to give [Mo(CO)2(L2-κ1P)(L)(η5-C5H5)]BF4 (L=PMe2Ph 8b; PMePh28c; PPh38d), and 6a reacts with PMe3, PMe2Ph, PMePh2 and PPh3 to give [Mo(CO)2(L3-κ1P)(L)(η5-C5H5)]BF4 (L=PMe310a; PMe2Ph 10b; PMePh210c; PPh310d). No reaction was observed for the pentamethylcyclopentadienyl compounds 4b–6b with PMe3, PMe2Ph, PMePh2 or PPh3. These results are consistent
