Migration Reaction of a Silyl Group from a Phosphorus to a Carbonyl Oxygen in a Molybdenum Coordination Sphere

The reaction of Cp anion, C 5 H 4 CH 2 CH 2 P(TMS)Mes] m with (CH 3 CN) 3 Mo(CO) 3 leads to the formation of ( m 5 --C 5 H 4 CH 2 CH 2 --P(TMS)Mes)Mo(CO) 3 ] m , which then reacts with MeI to give a metallaphosphacyclopropane complex with silyl migration.
