Abstract

Abstract A convenient two step synthesis of Rh 4(CO) 12 at room temperature and atmospheric pressure is reported. This involves reduction of the hexachlororhodate(III) anion to dicarbonyldichlororhodate(I) anion with copper metal, followed by further reduction with carbon monoxide and water in presence of sodium citrate buffer. Yields of 86–99% are obtained.
