Abstract

In situ reduction of Cp*ReO3 by PPh3 to form (Cp*ReO)2(µ-O)2 allows catalytic deoxygenation of epoxides, however, conproportionation between the ReV and ReVII species to form clusters of {(Cp*Re)3(µ-O)6}2+(ReO4)2 and new compound {(Cp*Re)32-O)33-O)3ReO3}+(ReO4) leads to removal of rhenium from the catalytic cycle and loss of activity.
