General Introduction

Tribenzylboranes and alkylbenzylboranes can be prepared by the methods described for the synthesis of trialkylboranes[‌1‌] (see Section ‌6.1.38‌). Previous published information on these methods is available in Houben–Weyl, Vol. 13/3a, p 13. However, care should be taken at the isolation step to avoid hydrolysis. In contrast to trialkylboranes which are not readily hydrolyzed, benzylboranes are sensitive to water. For example, tribenzylborane on treatment with water is readily transformed into dibenzylhydroxyborane.[‌2‌]
