Abstract

A novel isopentatungstate-supported metal carbonyl derivative KH[(CH3)4N]3{[Re(CO)3]4[(μ2-OH)(μ3-O)(W5O18)]}·6H2O (1) has been synthesized and characterized. Compound 1 represents the second example of isopolyoxotungstate-supported metal carbonyl derivative. The catalysis of 1 for alkene epoxidation with H2O2 was investigated, and was found to efficiently catalyze the epoxidation of cyclooctene with high conversion (98.9%) and excellent selectivity (99%). Furthermore, the solution behavior of the polyanion 1 was also explored using electrospray ionization mass spectrometry.
