Abstract:

Using cheap catalysis to substitute expensive metal and low cost carbon monoxide to replace hydrogen or phosgene has been pursuing by the people for many years. The paper reviewed the selenium catalyzed carbonylation reaction such as the carbonylation of carbon, nitrogen, oxygen and sulfur containing compounds and high selective reduction of some compounds based on the Se/CO/H2O system and introduced some new progress. Catalytic amount selenium readily activated carbon monoxide under very mild conditions to synthesize a series of fine chemicals and biochemicals directly. Catalyst selenium combined advantages from heterogeneous catalysis and homogeneous catalysis is a typical example of reaction process transfer catalysis. Selenium catalyzed carbonylation reaction has been characterized by high conversion, atom economical selectivity and environmentally benign and is superior to the traditional multi step method which involves the use of phosgene.

Key words: selenium-catalyzed carbonylation, selective reduction, unsymmetrical urea, phosgene, carbonyl exchange reaction, reaction process transfer catalysis
