The primary alcohols lad and ethers 4a-b were effectively reduced into the corresponding hydrocarbons 2 by HSiEt3 in the presence of catalytic amounts of B(C6F5)3. The secondary alkyl ethers 4g,h underwent cleavage and/or reduction under similar reaction conditions to produce either the silyl ether
HSiR 3 /cat-B(C 6 F) 3 induced dealkylation or reduction of esters of phosphorus at 20°C. 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 rati
