Platinum-mediated B–H methoxylation of bis(pyrazolyl)borate

Author affiliations

Abstract

A new bis(pyrazolyl)dihydridoborato diphenylplatinum(II) complex was found to react with methanol to form H2 and a new diphenylplatinum(II) complex supported by bis(pyrazolyl)dimethoxyborate. When performed in CD3OD, in addition to the expected installation of OCD3 fragments on the B-center and concomitant formation of H–D, deuteration of PtII(C6H5)2 fragments was observed. In contrast, dissolution of the bis(pyrazolyl)dimethoxyborato diphenylplatinum(II) complex in CD3OD led to neither deuteration of PtII(C6H5)2 fragments nor substitution of B-bound methoxy fragments. A mechanism discussing the role of the PtII-center is presented.
