Abstract
AbstractMild nucleophilic substitution reactions of benzhydrylic, benzylic, allylic, and simple aliphatic alcohols with sulfonamides, benzamide, and 4‐nitroaniline in the presence of 12‐phosphotungstic acid as an efficient, eco‐friendly, cheap, and air‐ and moisture‐tolerant catalyst for the construction of C–N bonds has been investigated. The amine derivatives were obtained in good yields (up to 98 %). The reusable nature of the 12‐phosphotungstic acid makes this protocol more attractive.(© Wiley‐VCH Verlag GmbH & Co.
