トリアルキルボランの反応(第2報)トリアルキルボランと芳香族ニトロ化合物との反応

抄録

Reaction of trialkylborane with nitrobenzene derivatives was examined. Reaction of nitrobenzene (I) and tricyclohexylborane (II) was found to proceed in ethanol or without a solvent and gave N-cyclohexylaniline (IIIa) and nitrosobenzene (IV), respectively reaction of II with IV yielded IIIa. Generally N-alkylaniline derivatives were obtained in analogous reaction. 4-Chloronitrobenzene (IX) gave azo or azoxy compound with N-alkyl-4-chloroaniline, and m-dinitrobenzene (XIV) gave m-dinitrobenzene (XV).
