Chemoselective reductions of alkenes, α,β-unsaturated carbonyl compounds, nitro and nitroso compounds, N,N-hydrogenolysis of azo and hydrazo functions as well as simultaneous reduction and hydrodehalogenation of substituted aryl halides, including bulkier substrates, were achieved by catalytic transfer hydrogenation (CTH) using mesoporous PdMCM-41 catalyst. The yields were practically unaffected upon
通过催化转移加氢实现烯烃,α,β-不饱和羰基化合物,硝基和亚硝基化合物的化学选择性还原,偶氮和肼基官能团的N,N-氢解以及同时还原和加氢脱卤化包括芳烃在内的卤代烷。 (CTH)使用中孔PdMCM-41催化剂。收率实际上不受催化剂再循环的影响。此外,在不影响任何其他可还原官能团的还原的情况下完成了CTH过程。
