Reaction Steps

Phenylphosphine dichloride, C6H5PCl2, was the only product detected when benzene and PCl3 were fed to the catalytic reactor. A mixture of o, m, and p-tolylphosphine dichloride, CH3C6H4PCl2, was the only organic product detected when toluene and PCl3 were used as the starting material. A small amount, < 1%, of POCl3 was observed. A mixture of α- and β-naphthylphosphine dichloride, C10H7PCl2, was produced, along with a small amount of POCl3 when naphthalene and PCl3 were used as the feed. A small amount of 2,5, dimethyl phenylphosphine dichloride was detected when p-xylene and PCl3 were used as the feed. Traces of toluene, POCl3 and an unidentified product were observed with the latter. The results are summarized in more detail in Table VI.
