Structure and formation of the first (-O-Te-N-)4 ring.
A twelve-membered macrocycle featuring the periodic -O-Te-N- sequence was obtained from the reaction of a β-(N,N-dimethylcarbamoyl-chalcogeno)-alkenyl ketone with hydroxylamine-O-sulfonic acid. A computational study suggests that the ring is assembled by spontaneous catenation of an intermediate isotellurazole-N-oxide.
