Abstract

The synthesis of unsymmetrical pincer ligands by reactions of diphenyl disulfide and diphenyl diselenide with bis(2-chloroethyl) ether in the system hydrazine hydrate–KOH was accompanied by the formation of 1,2-bis(phenylsulfanyl)ethane, 1,2-bis(phenylselanyl)ethane, and 1-(phenylselanyl)-2-(phenylsulfanyl)ethane as by-products with an overall yield of 23% as a result of nucleophilic cleavage of the C–O–C bond in the initial ether.

在水合肼-KOH体系中，硫代二氯硫醚与硫代氯酸酯键的亲核裂解

摘要

在水合肼-KOH体系中，二苯基二硫化物和二苯基二硒化物与双（2-氯乙基）醚反应合成不对称的钳形配体，同时形成1,2-双（苯基硫烷基）乙烷，1,2-双作为副产物，有（苯硒基）乙烷和1-（苯硒基）-2-（苯硫基）乙烷，由于初始醚中C–O–C键的亲核裂解，总收率为23％。
