low reactivity of the chlorine in 7-methyladenines, these compounds were converted into their salts (II, III). The formation of positively-charged carboniumions on protonation enhances the electrophilicity of the molecule, and facilitates replacement of the chlorine by sulfur. In addition to 2-thioadenine (IV), condensation of the salt (II) with thiourea gave some of the sulfide (V). 2-Amino-6-chloro-7-methylpurine
鉴于氯在 7-甲基腺嘌呤中的低反应性,这些化合物被转化为它们的盐 (II, III)。质子化时带正电的碳正离子的形成增强了分子的亲电性,并促进了氯被硫置换。除 2-硫腺嘌呤 (IV) 外,盐 (II) 与硫脲缩合得到一些硫化物 (V)。2-氨基-6-氯-7-甲基嘌呤(IX)得到6-硫-7-甲基鸟嘌呤(X)和2-氨基-6-甲硫-7-甲基嘌呤(XI)。
