Tetraphenylstibonium triflate

Tetraphenylstibonium triflate (PhtSbOTf liM) has been reported to be an effective catalyst for oxirane ring opening. Thus, otherwise unreactive cyclohexene oxide reacted smoothly with diethylamine in the presence of (134) (CH2CI2,40 C, 20 h) to give ( )-2-diethylaminocyclohexanol in 75% yield. "...
