Description Zinc phthalocyanine with PEG-400 was established as a catalytic system for chemo and regioselective
reduction of aromatic nitro compounds to corresponding amines. A large range of reducible functional
groups such as acid, amide, ester, halogen, lactone, nitrile, N-benzyl, O-benzyl, hydroxy and heterocycles
were well tolerated. Direct synthesis of benzotriazole from O-dinitrobenzene was achieved for the first
time. The present catalytic system was successfully employed for the reduction of carbonyl and ester
compounds to corresponding alcohols and reductive amination of benzaldehydes with primary amines to
form corresponding secondary amines. Remarkable advantages of the present catalytic method include
low loading of metal, avoidance of toxic ligands and high isolated yields. The catalyst was recyclable up
to four times without any loss of selectivity and activity.
