“…The products are benzene, diphenylamine, triphenylamine, and a little aniline (197). The formation of diphenylamine, for instance, might conceivably be represented by equations 202 to 206, 2 CeHsCl + 4 Na -> 2 NaCl + 2 C,H6Na (202) 2 C,H5Na + 2 NHS -» 2 C6H6 + 2 NaNH2 (203) C6H6C1 + NaNH2 -> C6H5NH2 + NaCl (204) CsHeNH2 + NaNH2 -> NH3 + C6H5NHNa (205) C8H6NHNa + C6H6C1 -> (C6H6)2NH + NaCl (206) but it has been found that reactions of the type expressed in equation 206 do not occur in liquid ammonia under such conditions (199,51).…”
