Formation of a 2,5-diborabicyclo(2.1.1)hexane derivative and its conversion to a tetracarbahexaborane: dedicated to Professor Worfsang Beck on the occasion of his 60th birthday
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 t...

| Riassunto: | 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 (tBuBCHCCMe2)2 dimer and the rearrangement to 2 are novel reactions. |
