The title phosphine-isocyanides were obtained by reaction of 2-lithioaryl isocyanides with diarylchlorophosphines. They cyclize to 1,3-benzazaphospholes with cleavage of their two aryl–P bonds upon treatment with an excess of lithium in THF. Their P═CH2 ylids spontaneously evolve to give λ5-1,4-benzazaphosphinines. Their complexation by gold(I), palladium(II), and nickel(II) chlorides has been investigated. An original pincer diphosphine–carbene complex has been obtained with palladium. The new products have been characterized by X-ray crystal structure analysis.
