A novel synthesis of 2-per(poly)fluoroalkyl-1H-benzimidazoles or 2-per(poly) fluoroalkyl benzothiazoles
摘要:
A new method for the preparation of 2-per(poly)fluoroalkyl-1H-benzimidazoles or 2-per(poly)fluoroalkyl benzothiazoles from reaction of readily available alpha-per(poly)fluoroalkyl aldehydes with o-phenylenediamine or 2-aminobenzenethiol is presented. A possible reaction pathway is suggested. (C) 1999 Elsevier Science S.A. All rights reserved.
