Treatment of a three-membered metallacycle Cp*(CO)Feκ2(Si,P)-SiMe2PPh2} (1) with substrates of the type RnEH (ERn = OH, OMe, OtBu, OPh, SpTol, NEt2, NPhH, PPh2, and PPhH) results in the instantaneous formation of the ring-opening products Cp*(CO)Fe(PPh2H)(SiMe2ERn). In these reactions, 1,2-addition of the substrates occurs exclusively across the silicon−phosphorus bond in 1. The structures of the
