• ω-HALOALKYL AND ω -AMINOALKYL SULPHIDES CLEAVAGE OF THE ALKYL–SULPHUR BOND

  日期：1959.2.1

  In the homologous series of p-chlorophenyl ω-chloroalkyl sulphides (I), the first and second members reacted abnormally with amines to yield 1, ω-bis(p-chlorophenylmercapto)alkanes (II). The fourth member of the series reacted normally to produce 4-aminobutyl p-chlorophenyl sulphide (III). The formation of II is explained on the basis of an alkyl–sulphur bond cleavage. The members of the p-chlorobenzyl series (VI) in general reacted with amines to form the expected aminoalkyl sulphides (VII). However, the p-chlorobenzyl chloroalkyl sulphides (VI) were thermally labile and decomposed to p-chlorobenzyl chloride and a sulphur component. A cyclic sulphur component originated from VI whose chloroalkyl carbon chain was 4, 5, or 6. The thermal degradation of VI is explained through a sulphonium salt cleavage

  在p-氯苯基ω-氯烷基硫醚（I）的同系列化合物中，第一和第二个成员与胺反应异常，生成1，ω-双(p-氯苯基硫醚)烷烃（II）。该系列的第四个成员正常反应，产生4-氨基丁基p-氯苯基硫醚（III）。II的形成基于烷基-硫键的断裂解释。p-氯苯甲基系列（VI）的成员通常与胺反应，形成预期的氨基烷基硫醚（VII）。然而，p-氯苯基氯烷基硫醚（VI）在热力学上不稳定，分解成p-氯苯甲基氯化物和硫组分。VI的一个环状硫组分来源于其氯烷基碳链为4、5或6。VI的热降解通过磺隆盐断裂来解释。

  A method has been developed for the synthesis of a new heterocyclic system III. When 2-β-chloroethoxybenzyl chloride (XI) was heated with thiourea in alcohol solution, S-(2-β-chloroethoxybenzyl)isothiuronium chloride (XII) was formed which on cleavage with aqueous alkali in high dilution yielded 2,3-dihydrobenzo(f)-1,4-oxathiepin (III). Derivatives of III with substituents such as methyl, t-butyl, chlorine, and nitro in the 7 and 9 positions were prepared in high yields from the corresponding substituted 2-β-chloroethoxybenzyl chlorides. The presence of substituents in the position ortho to the chloroethoxy group of XII had no retarding effect on the cyclization to XIV.
