Conclusions

  1. 1.

    The radical arylation of thiourea and N,N'-diphenylthiourea using N-nitrosoacetanilide and N-nitro-so(a cet-p-toluidide) as the source of aryl radicals gave the N-aryl-N,N'-diphenylisothiuronium compounds, which were isolated as the picrates.

     
  2. 2.

    The N-nitrosoacetanilides are more efficient arylating agents for N,N'-diphenylthiourea than phenylazotriphenylmethane.
