The reaction of trialkylphosphites or related P-nucleophiles with benzothiete () leads to zwitter ionic species, which show an Arbuzov - like rearrangement to the products and , respectively. New heterocyclic ring systems are generated in the case of cyclic esters. The normal SN2 reaction leads to the 1:2 adducts , whereas in an SN1 process the 1:1 adduct is formed.
亚磷酸三烷基酯或相关的P-亲核试剂与苯并噻吨()的反应导致两性离子物种,分别对产物和表现出类似Arbuzov的重排。在环状酯的情况下,产生了新的杂环系统。正常的S N 2反应生成1:2的加合物,而在S N 1过程中生成1:1的加合物。
