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.

双（吡唑基）硼酸酯的铂介导的BH甲氧基化。

发现新的双（吡唑基）二氢硼基二苯基铂（ii）配合物与甲醇反应形成H 2和由双（吡唑基）二甲氧基硼酸酯负载的新的二苯基铂（ii）配合物。在CD3OD中执行操作时，除了预期的OCD3片段在B中心的安装以及HD的伴随形成之外，还观察到了PtII（C6H5）2片段的氘化。相反，双（吡唑基）二甲氧基硼酸二苯基铂（ii）络合物在CD3OD中的溶解既不会导致PtII（C6H5）2片段的氘化，也不会导致B结合的甲氧基片段的取代。提出了讨论PtII中心作用的机制。
