Halide abstraction chemistry has been exploited to generate the cationic terminal borylene complex 1, which reacts with Ph3P[DOUBLE BOND]S or Ph3As[DOUBLE BOND]O to form 3 and 4. In the case of the corresponding reaction with Ph3P[DOUBLE BOND]O, the intermediate 2 can be isolated, which provides evidence for a two-step addition/substitution mechanism for the overall metathesis reaction.
