Recent studies on novel reactions of thioamides, thioureas, and related compounds with various radical-forming agents such as phenylazotriphenylmethane, N-nitrosoacetanilides, and aryldiazonium salts are reviewed. The aryl radicals are shown to add t

The reaction of thiourea, N-phenyl-, and N,N'-diphenylthiourea with phenyl radicals proceeds by two competing pathways with the formation of the corresponding S-phenylisothiouronium compounds and bis(formamidine) sulfides. The ratio of the product yi

X-Ray structural analysis has been used to establish the structures of the heterocyclic oxidation products of N-arylthioureas. The oxidation product of N,N'-diphenylthiourea (Hugershoff 's base) is 2-[N-phenyl-N-(phenylamino-phenylimino-methyl)] amin

1. Reaction of azobisisobutyronitrile with thiobenzanilides results in addition of 2-cyanoisopropyl radicals to the sulfur atom, and subsequent reactions of the adduct-radical result in the formation of the corresponding imidosulfides and/or S-cyanoi

1. The homolytic arylation of thiosemicarbazide and acetone thiosemicarbazone with phenyldiazonium borofluoride in the presence of CuCl2·2H2O and with p-nitrophenyldiazonium borofluoride in absence of the copper salt forms S-arylisothiosemicarbazide

1. We have demonstrated the formation of aryl free radicals by the decomposition of phenyl and p-methoxyphenyl borofluorides by means of ferrocene by both preparative and EPR methods. 2. The system ArN2BF4-ferrocene can be used for S-arylation of thi

1. N-Allyl and N,N′-diallylthiourea, like other N-substituted thioureas, are readily arylated by phenyl- and p-nitrophenyldiazonium fluoroborate in the presence of CuCl2 to form the corresponding S-arylisothiuronium compounds which were isolated as
