摘要：

Weak nucleophiles for strong activation: The reversible activation of dihydrogen by an electron-deficient phosphine, (C 6F 5)PPh 2, in combination with the Lewis acid B(C 6F 5) 3 at -80 °C was accomplished. The catalytic hydrogenation of olefins proceeds through protonation and subsequent hydride attack. Electron-deficient phosphines and diarlyamines were demonstrated to be viable Lewis bases for the reaction, thus allowing catalyst loadings of 10 to 5 mol %.
