Through hydride or fluoride abstraction , the dication 1 reacts with BH 3 · THF (PF 6 − ) to give monocationic complexes in which a hydrido (fluoro) ligand bridges a WW triple bond (WW single bond). The unusually high electrophilicity of 1 arises from the combination of positive charge and metal–metal multiple bond. The counterion in each case is PF 6 .
