yields (80–90%). Their reactivity has been tested toward various electrophiles. It illustrates the wide scope of synthetic utility of these reagents (alkylation with primary and secondary alkyl bromides, hydroxy alkylation, acylation) and provides new routes to esters and α-chloroesters.
锂在0至-5°C下于THF中的α,α-二氯酸酯和α,α-二取代的α-单卤代酸酯上反应,导致相应Reformatsky试剂的硫代类似物形成,收率很高(80-90%)。它们的反应性已针对各种亲电子试剂进行了测试。它说明了这些试剂的广泛合成用途(与伯烷基和仲烷基溴的烷基化,羟烷基化,酰化),并提供了制备酯和α-氯代酯的新途径。
