Organoboranes, alkyl exchange reactions

This article will discuss the alkyl exchange and thermal isomerization reactions of organoboranes and various syntheses, properties, and reactions of heterocyclic organoboranes with one boron atom and will present a summary of heterocyclic organoboranes with two or more boron atoms. 

Exchange reactions between organoboranes R3B and trihalides BX3 afford alkylhaloboranes without loss of alkyl groups, although such reactions require temperatures generally > 150°, and a mixture of mono- and di-haUde normally results and has to be separated by low pressure distillation ...
