title: Unexpected formal insertion of CO2 into the C-Si bonds of a zinc compound.
abstract: Reaction of [κ2-PR2C(SiMe3)Py]2Zn (R = Ph, 2a; iPr, 2b) with CO2 affords the products of formal insertion at the C–Si bond, [κ2-PR2CC(O)O(SiMe3)Py]2Zn (R = Ph, 3a; iPr, 3b). Insertion product 3b was structurally characterized. The reaction appears to be a stepwise insertion and rearrangement of CO2 based on kinetic data.
