摘要：
2-Amino-4-arylthiazoles 1a-d, 2-aminobenzothiazole (2) and 2-aminobenzimidazole (3) react with tetracyanoethylene (TCNE) to give dithiazolylazomethane, thiazolone derivatives 8 and 13 and tricyanovinylation products 6 and 14 as well as the benzimidazo[1,2 a]pyrimidine 17. The reaction of donors 1-3 with 2,3,5,6-tetrachloro-1,4-benzoquinone (CHL) gave bisthiazolylaminochloranils 18 and 2-monobenzimidazol-aminotrichloro-1,4-benzoquinone (19). The mechanism of formation of these products has been interpreted.
