| Abstract
| - Treatment of a three-membered metallacycle Cp*(CO)Fe{κ2(Si,P)-SiMe2PPh2} (1) withsubstrates of the type RnEH (ERn = OH, OMe, OtBu, OPh, SpTol, NEt2, NPhH, PPh2, andPPhH) 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 acrossthe silicon−phosphorus bond in 1. The structures of the products have been unequivocallydetermined by spectroscopic data and X-ray diffraction analysis.

In these reactions, 1,2-addition of the substrates occurs exclusively across the silicon−phosphorus bond in 1. The structures of the products have been unequivocally determined by spectroscopic data and X-ray diffraction analysis.
