摘要: Abstract The complexes [Rh(diene)(L-L′)](BF 4 ), and [RhCl(CO)(L-L′)] (diene=COD 1,5-cyclooctadiene; L-L′=P(bzN)Ph 2 , P(bzN) Ph, 3 PePy, or PePy bzN=2-(dimethylaminomethyl)phenyl, n =P(CH CH Py) Ph 3− ; Py=2-pyridyl; =1,2) are poor catalysts for the hydrosilylation of 1-hexyne, but excellent silylformylation 1-hexyne in tetrahydrofurane at atmospheric pressure room temperature.
