Reaction of 2,6-dimethylphenyl(diphenylmethylene)phosphine (1) with selenium in benzene leads to the compound 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 PC bond of 2c to give the selenophosphinate 3c. No reaction was observed between 1 and tellurium
2,6-二甲基苯基(二苯基亚甲基)膦(1)与硒在苯中的反应生成化合物P -2,6-二甲基苯基-C,C-二苯基硒代膦(2c)。化合物2c在室温下是稳定的,但在加热时分解,且原料部分再生。乙醇加成2c的PC键,得到硒代膦酸酯3c。在1和碲之间未观察到反应。
