제목 Pd NHC complexes as catalyst for reductive carbonylation of nitrobenzene for generating urethanes
초록 Carbamates have been widely used due to their versatility such as intermediates in pharmaceuticals, pesticides, fertilizers or precursors of isocyanates. The conventional process for the production of carbamates involves the toxic usage of phosgene. The reductive of carbonylation of aromatic nitro compounds with carbon monoxide in the presence of alcohols has drawn much attention as a phosgene-free alternative to carbamates. There have been numerous attempts to afford carbamates from the reductive carbonylation of nitrobenzene facilitated by various complexes of transitional metals. In this research, N-heterocyclic carbene (NHC)-palladium(II) complexes have been investigated as active catalysts for the synthesis of carbamates. The results showed that the 97% yield of carbamates was obtained under the conditions at 1600C in 2 h in the presence of (NHC)-palladium(II) as main catalyst.
