Selective reduction of alkenes,alpha,bet-unsaturated carbonyl compounds,nitroarenes,nitroso compounds,N,N-hydrogenolysis of azo and hydrazo functions as well as simultaneous hydrodehalogenation and reduction of substituted aryl halides over PdMCM-41

摘要

Chemoselective reductions of alkenes,alpha,beta-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 recycling of the catalyst.Further,the CTH process is accomplished without affecting the reduction of any other reducible functional group.
