  烷基卤化物和苄基卤化物中的卤素被4-羟基-2-巯基-6-甲基嘧啶生成的阴离子亲核取代的特殊特征

  摘要：

  The nucleophilic substitution of halogen (chlorine, bromine, and iodine) in alkyl and benzyl halides has been effected in aqueous dioxane media with S-and O-anions generated from 4-hydroxy-2-mercapto-6-methylpyrimidine. Under these conditions replacement of halogen proceeds by an S(N)2 mechanism and the reactivity of S-anions is 10 times greater than that of O-anions, which is in agreement with the results of ab initio quantum-chemical calculations of the electronic structure and total energy of transition states, carried out within the framework of the restricted Hartree-Fock method, basis 6-31G**.

  摘要：

  2-Alkyl(aralkyl)sulfanyl-6-methylpyrimidin-4(3H)-ones and 4-alkyl(aralkyl)oxy-2-alkyl(aralkyl)-sulfanyl-6-methylpyrimidines having similar or different substituents on the sulfur and oxygen atoms were synthesized by alkylation of sodium salts derived from 6-methyl-2-thioxo-1,2,3,4-tetrahydropyrimidin-4-one and 2-alkyl(aralkyl)sulfanyl-6-methylpyrimidin-4(3H)-ones with alkyl (propyl, ethyl, allyl) and aralkyl [benzyl, m-phenoxybenzyl, p-(1-adamantylbenzyl)] halides. The effects of the alkyl (aralkyl) halide nature and solvent polarity on the rate of nucleophilic substitution and product yield were studied.
