title: Syntheses and reactions of the bis-boryloxide O(Bpin)2(pin = O2C2Me4).
abstract: The reaction of the phosphine oxides, OPEt31 and OPn-Bu32 with pinacolborane (HBpin) results in phosphine oxide reduction and the formation of O(Bpin)23. In contrast, the phosphine oxide OPn-Bu3 reacts with HB(C6F5)2 or B(C6F5)3 to give only the donor-acceptor adducts. Compound 3 reacts with HNPt-Bu3 to give the phosphinimonium borate salt, [t-Bu3PNH2][(Bpin(OBpin)2]6, while reaction with Cp2ZrMe2 affords the species Cp2Zr(OBpin)27.
