Abstract

In 2006 Stephan et al. discovered that “metal-free” main group element Lewis acid–base pairs, like Mes 2 P(C 6 F 4 )B(C 6 F 5 ) 2 , 1 can reversibly activate H 2 . This finding triggered a search for a new type of hydrogenation catalysts. Similar to protonic–hydridic transition metal complexes such hydrogenation systems operate via a “bifunctional activation” or “ionic hydrogenation” mode with formal heterolysis of H 2 . For proper reactivity such Lewis ...
