摘要：
(Chemical Equation Presented) Some elements go both ways: The reaction of [LAl] (L=HC(CMeNAr)2, Ar = 2,6-iPr2C6H 3) with BArF3 (ArF = C 6F5) yields [LAlBArF3] (see scheme). Crystallographic studies and ab initio calculations show the formation of an Al-F bond, which shows the aluminum center having both Lewis base and Lewis acid character. © 2005 Wiley-VCH Verlag GmbH & Co.
