The authors report the discovery of a new catalyst for the reactions of aryl halides with trialkyl phosphites, namely, tetrakis(triethyl phosphite)Ni(O). They suppose that catalysis by the Ni(O) complex consists of two stages. The first is the oxidative addition of the aryl halide to the Ni(O) complex. The second is reductive elimination with the regeneration of the catalyst. The proposed scheme is confirmed by the results of the methods of molecular spectroscopy. The formation of a tetrahedral paramagnetic complex is characterized by a weakening and broadening of the /sup 31/P signal and by a downfield shift of the compounds by 20-60 ppm.
