产品介绍	对甲苯磺酰氯是一种有机磺酰氯，主要用于通过形成磺酸盐将羟基转化为良好的离去基团. 对甲苯磺酰氯可用于以下过程：与 N-甲基咪唑一起用于羧酸与醇或硫醇的酯化或硫酯化反应。作为添加剂，在不存在配体的条件下，通过氯化钯催化的芳基硼酸均相偶联，提高对称联芳基的产率。作为酮的-氯化反应的正氯源。在heterodoxy acid存在下，醇和酚的无溶剂甲苯磺酰化反应。在三氟甲基磺酸银存在下，作为2-炔基苯甲醛肟与酚的反应活化剂，形成1-芳氧基异喹啉。作为催化剂，以苯二醇为原料进行对称双二苯甲基醚的无溶剂制备。 p-Toluenesulfonyl chloride is an organic sulfonyl chloride mainly used to convert hydroxyl groups into good leaving group by forming sulfonates.
