Ushbu maqolada 1-naftil sirka kislotasining sintezi naftalin va monoxloroatsetat kislotasi o‘rtasida alyuminiy asosidagi katalizator ishtirokida olib borilishi o‘rganiladi. Reaksiya yuqori haroratda olib boriladi, bunda alyuminiy monoxlorsirka kislotani faollashtirib, reaktiv karbokation oraliq birikmasini hosil qiladi. Ushbu oraliq mahsulot naftalinning α-pozitsiyasiga elektrofil almashinish reaksiyasi orqali birikib, gidrolizdan so‘ng 1-naftilsirka kislotani hosil qiladi.. Yakuniy mahsulot erish harorati, IQ spektri va xromatografik usullar yordamida tavsiflangan. Ushbu usul sanoat sharoitida qo‘llanishi mumkin bo‘lgan oddiy, samarali va xomashyolarga boy sintez yo‘nalishi sifatida taklif etiladi.
