Epoxidation of cyclooctene with hydroperoxy sultams catalyzed by molybdenum boride

The hydroperoxy sultams have been investigated in epoxidation reaction of cyclooctene catalyzed by MoB. It was shown hydroperoxides can function as the epoxidation agents. The high epoxides yields were observed in the case of hydroperoxy sultams with chlorine atoms. ▪ The hydroperoxy sultams (HPS) have been investigated in catalytic epoxidation reaction of cyclooctene. We have found that HPS can function as the epoxidation agents in the presence of molybdenum boride MoB as a catalyst. The reaction was sensitive to steric as well as electronic factors. The high epoxides yields were observed in the case of hydroperoxy sultams with chlorine atoms and especially favorable was hydroperoxide structure with α-position of chlorine atom to bond of nitrogen with aromatic ring.
