Nickel-catalyzed manipulation of tertiary phosphines via highly selective C–P bond cleavage

A catalytic cycle involving oxidative addition of nickel(0) with a carbon-carbon single bond in the three-membered ring of diarylmethylenecyclopropa[b]naphthalenes, highly selective cleavage of the C-P bond, and migration of the aryl group of phosphine consequently provides a new type of bulky phosphine in excellent yields.
