PHASE TRANSFER CATALYSIS IN SOLID–LIQUID SYSTEM AS A SELECTIVE METHOD OF MONO-ALKYLATION OF α-SULFONYL THIOESTERS
摘要:
alpha-Phenylsulfonyl methylthioacetate gave monoalkylated products in high yields when treated with alkyl halides in the presence of K2CO3 with TEBAC in CH2Cl2, at r.t. The superiority of this method over that in the homogeneous phase is discussed.
