Reaction of the tungsten methylidyne complexes (dmpe)2W(X)
CH (X = Cl, OTf) with HB(C6F5)2yields zwitterionic compounds upon electrophilic attackof the methylidyne ligand, in which the methylidynehydrogen is strongly 
-agostic (X = Cl) or is transferredto the tungsten center (X = OTf). Removal of hydridefrom the coordinated HB(C6F5)2 with [Ph3C]+[B(C6F5)4]-gives a cationic borylalkylidyne hydride species.
