Remarkable Difference in Reactivity between Diorganodichlorosilanes and Diorganodifluorosilanes, Computed Properties of 312-40-3, the publication is Organometallics (1995), 14(5), 2136-8, database is CAplus.
The [CH2C(O)CPh2]2- dianion reacted with R2SiCl2 (R = Ph, CH3, Et) to give cyclic products I but with R2SiF2 cyclic products II (R = Ph, Et) were formed. The structures of I and II (R = Ph) were determined by single-crystal x-ray diffraction. A reason for the difference in the regioselectivity of the reactions of the dianion with R2SiCl2 and R2SiF2 is suggested.
