An easily recoverable and recyclable homogeneous polyester-based Pd catalytic system for the hydrogenation of α,β-unsaturated carbonyl compounds
Highlights
- •
- trans-[Pd(OAc)2(L)2] was synthesized from Pd(OAc)2 and the poly(l-lactide) (L).
- •
- trans-[Pd(OAc)2(L)2] was used as catalytic precursor in hydrogenations.
- •
- trans-[Pd(OAc)2(L)2] is a homogeneous catalytic precursor.
- •
- The homogeneous catalyst can be easily recovered from the reaction mixture.
- •
- The catalytic system maintained its activity in recycle experiments.
Abstract
Homogeneous
catalysis is an efficient tool to carry out hydrogenation processes but
the major drawback is represented by the separation of the expensive
catalyst from the product mixture. In this view we prepared a
polyester-based Pd catalytic system that offers the advantages of both
homogenous and heterogeneous catalyses: efficacy, selectivity and
recyclability. Here its application in the hydrogenation of selected
α,β-unsaturated carbonyl compounds is described.
