Rearrangement of the dihydrobromide of octahydro-3,7-dimethoxy-1,5-diphenyl-1,5-diazocine
Abstract
The dihydrobromide of octahydro-3,7-dimethoxy-1,5-diphenyl-1,5-diazocine (I) reacts with dimethyl sulphoxide at room temperature to give exclusively 1,5-bis-(p-bromophenyl)octahydro-3,7-dimethoxy-1,5-diazocine (II).
