Annotatsiya
Ushbu tadqiqot ishida m-krezolni turli xil sharoitlarda xlorasetilxloid bilan reaksiyalari olib borildi. m-Krezolni katalitik miqdordagi FeCl3, FeCl3×6Н2О, ZnCl2, Fe2(SO4)3 va TAA lar ishtirokida xlorasetilxlorid bilan reaksiyasi olib borilgangada, izomerlar aralashmasi hosil bo‘lishi aniqlandi. Individual modda sintez qilish maqsadida tadqiqotlar davom etirilganda, benzol eritmasida m-tolilxlorasetat sintez qilish uslubi topildi. Ushbu reaksiyaning reaksiya mexanizmi ishlab chiqildi va nazariy jihatdan asoslab berildi. m-Tolilxlorasetatni 4-metilfenol bilan nuklefil almashinish reaksiyasiya benzol, aseton, dioksan, DMF, DMSO eritmalarida olib borildi. Reaksiya unumi DMSO eritmasida yuqori bo‘lib, m-tolil-4-metilfenoksiasetat unumi 95% ni tashkil etdi.
