摘要：

A framework rearrangement and a migration of a hydrogen atom result in the formation of the carborane 2 from the bridged boretane 1. The crystal structure analysis shows that the four-membered ring in 1 is extremely folded. This suggests a 1,3-transannular interaction between the free p orbital at the B atom and the exocyclic double bond at the C atom. Both the formation of 1 from the nonisolable (tBuB - CH = C = CMe2)2 dimer and the rearrangement to 2 are novel reactions.
