Abstract:CO selective reduction of aromatic nitro compounds catalyzed by Ru 3(CO)9(PETPP)3 complex (PETPP= P[C 6H4-p-(OC2H4)nOH] 3) in aqueous/organic two-phase system was investigated. The catalyst displayed good catalytic activity for the reduction of o-ClC6H 4NO2 at 140  C and Pco= 4 MPa: conversion of o-ClC 6H4NO2 was 99.2% and selectivity toward the desired amines was higher than 99%. After the reduction the catalyst in water phase could be easily separated from the organic phase containing product and could be employed in the successive reaction runs. The conversion of aromatic nitro compound could be kept higher than 88% after 4 recycles of the catalyst.
