摘要:
A process is described for the preparation of 3-alkylsulfinylbenzoyl derivatives of the formula (IIIa) by reaction of 3-alkylsulfinylbenzoic acids of the formula (Ib) with compounds of the formula (II) in the presence of a chlorinating agent and a base.In the formulae specified above, Y is a radical such as pyrazolyl and cyclohexanedionyl. R1, R2 and R3 are radicals such as halogen, nitro, cyano and alkyl.描述一種製備式(IIIa)3-烷基亞磺醯基苯甲醯基衍生物之方法,其係藉由式(Ib)3-烷基亞磺醯基苯甲酸與式(II)化合物在氯化劑及鹼存在之反應下。在上述指明的式中,Y為基團諸如吡唑基及環己二酮基。R1、R2和R3為該等基團諸如鹵素、硝基、氰基及烷基。
