Abstract
The homogeneous ruthenium complex [Ru IICl 2(bpea)(PPh 3)], where bpea = N,N-bis-(2-pyridylmethyl)ethylamine, has been immobilised on an amorphous AlPO 4 support through phosphamide bonds that are comparatively more stable than organosilane bonds. The catalyst was characterised by means of UV–vis and DRIFT and its activity was compared to that of the homogeneous complex in the liquid-phase hydrogenation of a range of alkenes. The heterogenized catalyst exhibited very good activities and excellent reusabilities (up to 25 runs) in the hydrogenation reaction.
