Article abstract of DOI:10.1016/0022-328X(83)80044-8

Reaction of 2,6-dimethylphenyldiphenylmethylene)phosphine (1) with selenium in benzene leads to the compoud P-2,6-dimethylphenyl-C,C-diphenylselenophosphene (2c).Compound 2c is stable at room temperature, but decomposes on heating with partial regeneration of the starting materials.Ethanol adds to the P=C bond of 2c to give the selenophosphinate 3c.No reaction was observed between 1 and tellurium.
