摘要：
HSiR3/cat-B(C6F)(3) induced dealkylation or reduction of esters of phosphorus at 20degreesC. A specific conversion to P-silylesters occurred by reaction with tertiary silanes. In contrast, free phosphines were observed in the reaction with mono- or disubstituted silanes. A mechanism was proposed to rationalize these results. (C) 2002 Elsevier Science Ltd.
