Skeletal rearrangement of a boron-containing annulenic molecule into a macrocycle bridged by an electronically stabilized boron cation

Abstract

An annulenic molecule containing a three-coordinate chloroborane moiety, which exhibits a borane-olefin proximity effect, undergoes a skeletal rearrangement upon chloride abstraction, to generate a three-dimensional macrocyclic molecule featuring a borocenium...

A chelated borinium cation

“…To this end, in this report we target the synthesis of a chelated borinium cation. Such species are unknown, although Shoji and coworkers 25 have recently reported a borocenium cation in which the boron is bound to carbon which is linked to a bound cyclopentadienyl ring.…”
