Palladium complexes with different polymer ligands have been studied in hydrogenation and isomerisation of 2-propen-1-ol. Isomerisation of 2-propen-1-ol into propanal under hydrogenation conditions was observed over the palladium complexes with copolymer styrene and divinylbenzene (DVB) modified with iminodithiol groups (PdCl 2 -CoP-SH). Palladium complexes with linear poly(2-vinylpyridine) (PdCl 2 -PVP) and aminocellulose (PdCl 2 -Cell-NH) were active for 2-propen-1-ol hydrogenation. XPS study of the initial catalysts as well as pre-treated with hydrogen and spent catalysts showed that Pd in active hydrogenation catalysts is reduced to Pd(0). Isomerisation catalyst PdCl 2 -CoP-SH includes mainly Pd(II). Catalytic activity and selectivity of the obtained polymer-metal complexes depend on the structure of polymer matrix and the functional groups. The mechanism of hydrogenation is discussed. |
