摘要:
A dechalcogenative method for the preparation of an allylic sulfide comprises contacting an activated chalcogenide of Formula (I) with a thiol of Formula (II) for a period of time sufficient to form an intermediate of Formula (III), and supplying sufficient activation energy to the intermediate of Formula (III), in a suitable solvent, preferably in the absence of a phosphine or other thiophile, to induce a [2,3]-sigmatropic rearrangement therein to form an allylic sulfide of Formula (IV), with concomitant loss of chalcogen Z, as set forth in the following reaction scheme, wherein X is an activating group selected from the group consisting of CN, S-pyridyl, S-heteroaryl, SO2-aryl, and SO3Y; Y is an alkali metal ion; Z is Se or S; R1, R2, R3, R4, and R5 are each independently H or a hydrocarbon moiety; and R is an organic moiety.
摘要(中):
用于制备烯丙基硫醚的脱钙方法包括使式(I)的活化硫属化物与式(II)的硫醇接触足够长的时间以形成式(III)的中间体,并将足够的活化能提供给 式(III)的中间体在合适的溶剂中,优选不存在膦或其他硫霉菌,以在其中诱导[2,3] -sigmatropic重排以形成式(IV)的烯丙基硫醚,并伴随损失 的硫族元素Z,如以下反应图解所示,其中X是选自CN,S-吡啶基,S-杂芳基,SO 2 - 芳基和SO 3 Y的活化基团; Y是碱金属离子; Z是Se或S; R 1,R 2,R 3,R 4和R 5各自独立地为H或烃部分; 并且R是有机部分。
