Mono- and di-(2-nitroguanidino)benzenes and some of their amino and nitro derivatives
摘要:
A method was developed for the synthesis of mono- and di-(2-nitroguanidino)benzenes and some of their amino and nitro derivatives, based on the reaction of aniline and phenylenediamines with S-methylisothionitrourea, followed by oxidation of the aminophenol-2-nitroguanidines or by nitration of aryl-2-nitroguanidines. It was shown that o-phenylenediamine reacts with S-methylisothionitrourea to form 2-nitraminobenzimidazole.
