A series of benzylideneamine N,C-chelate boron compounds have been found to undergo rapid multistructural transformations with UV irradiation, yielding new BN-cycloocta-1,3,6-triene ((4Z,6Z)-1,2,3,8-tetrahydro-1,2-azaborocine) and BN-cyclohepta-1,3,5-triene (2,7-dihydro-1H-1,2-azaborepine) derivatives with a tetrasubstituted B[double bond, length as m-dash]N unit quantitatively. The simple imine donor also lends itself to achieving photoreactivity in compounds with two phenyl substituents on boron, which is the first example for this type of organoboron photochemistry.

通过光异构化 将亚苄基亚胺N,C-螯合物硼化合物转变为带有四取代B [双键,长度为m-破折号]N单元的BN-环辛/环庚三烯

已发现一系列亚苄基胺N,C-螯合硼化合物在紫外线照射下进行快速多结构转化,从而产生新的BN-环辛-1,3,6-三烯((4 Z,6 Z)-1,2,3定量地具有四取代的B N单元的,8,8-四氢-1,2,-氮杂硼烷)和BN-环庚-1,3,5-三烯(2,7-二氢-1 H -1,2-氮杂硼平)衍生物[双键,长度为m-破折号]。简单的亚胺供体也有助于在硼上带有两个苯基取代基的化合物中实现光反应性,这是这类有机硼光化学的第一个例子。
