Abstract

The parent compounds of phosphanylboranes of the type (LA)H2P-BH2(LB) (LA = Lewis acid, LB = Lewis base) stabilised by Lewis acid/Lewis base have been synthesised by using perfluorinated main-group Lewis acids. The Lewis acid-phosphane adducts (C6F5)3BPH3, (C6F5)3BPPhH2 and (C6F5)3GaPPhH2 (3) were used as starting materials, which upon lithiation with nBuLi react with the chlorinated Lewis base ...
