Oxirane derivatives, ring-opening reactions

Derivatives of azete are only known as unstable reaction intermediates. Oxetane and azetidine are considerably less reactive than their three-membered connterparts (oxetane reacts with hydroxide anion 10 times more slowly than does oxirane), but nonetheless do undergo similar ring-opening reactions, for example oxetane reacts with organolithium reagents in the presence of boron triflnoride, or with cuprates, and azetidine is opened on heating with concentrated hydrochloric acid. Azetidininm ions react mnch more easily with nucleophiles. ... [Pg.597]

N2-Type processes are involved in the ring-opening reactions of oxirans, under mild conditions (by thiols, adsorbed on alumina), and in the ring-closure of a penicillin-derived enethiolate. ... [Pg.11]
