The addition of the Grignard 3,4,5-ArFMgBr to aluminum(III) chloride in ether generates the novel triarylalane Al(3,4,5-ArF)3·OEt2. Attempts to synthesize this alane via transmetalation from the parent borane with trimethylaluminum gave a dimeric structure with bridging methyl groups, a product of partial transmetalation. On the other hand, the novel alane Al(2,3,4-ArF)3 was synthesized from the parent
将格利雅3,4,5-Ar F MgBr添加到乙醚中的氯化铝(III)中,生成新的三芳基铝烷Al(3,4,5-Ar F)3 ·OEt 2。尝试通过将母体硼烷与三甲基铝进行重金属化合成该烷烃,得到具有桥连甲基的二聚结构,这是部分重金属化的产物。另一方面,新型的烷烃Al(2,3,4-Ar F)3是由母体硼烷和三甲基铝合成的。有趣的是,Al(2,3,4-Ar F)3的固态结构显示了由相邻的Al···F接触导致的延伸链结构。Al(3,4,5-Ar F)3·然后发现OEt 2是用频哪醇硼烷对羰基,亚胺和炔烃进行硼氢化的有效催化剂。
