Abstract

HSiR3/cat-B(C6F)3 induced dealkylation or reduction of esters of phosphorus at 20°C. A specific conversion to 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.
