The reaction of pentafluorobenzoic acid with 2-mercaptoethanol followed by modification of the reaction product by oxidationm halohydroxylation and (or) decarboxylation led to the formation of β-halo- and β-oxyethyl polyfluoroaryl sulfides, sulfoxides, and sulfones, initial compounds for the synthesis of fluorinecontaining 2,3-dihydro-1,4-benzothiazines, 2,3-dihydro-1,4-benzoxathiynes, and 2,3-dihydro-1
五氟苯甲酸与2-巯基乙醇的反应,然后通过卤代羟基氧化和(或)脱羧氧化反应产物的改性,导致形成β-卤代和β-氧乙基聚氟芳基硫醚,亚砜和砜,它们是合成的初始化合物含氟的2,3-二氢-1,4-苯并噻嗪,2,3-二氢-1,4-苯并噻吨酮和2,3-二氢-1,4-苯并噻二炔以及它们的S-氧化物和S-二氧化物分子内亲核功能紊乱。
