Heterolytic splitting of Si−H bonds was achieved by combining an oxidomolybdenum(VI) complex and the Lewis acid B(C 6 F 5 ) 3 , resulting in highly unusual molybdenum silanolate/hydridoborate ion pairs that were able to subsequently transfer both hydride and silyl group to a carbonyl substrate in a novel mechanism. The image shows the strong Lewis acidic boron center “capturing” the anionic hydride, whereas the silyl group remains with the Lewis basic molybdenum oxido unit.
