Abstract:
Amine and amide derivatives are important nitrogen sources in organic synthesis.
They have been synthesized by the aerobic N-alkylation of sulfonamides with alcohols.
Wilkinsons catalyst, ligand-free metal catalysts, and various heterogeneous catalysts were
efficient for this reaction. However, these catalytic systems actually required inert atmosphere
protection, high temperature, long reaction time, use of solvent, and large excess amount of
reagents. Therefore, the improvement of heterogeneous catalysts for the aerobic N-alkylation
of sulfonamides with alcohols is highly desirable. In this work, the catalysts were simply
synthesized by the impregnation of permanganate anions on synthetic hydrotalcite (SHT) and
commercial hydrotalcite (CHT) followed by the reduction with glucose. The amount of Mn in
the catalysts was varied to be 5, 10, and 20 wt%. The XRD patterns and TEM images of the
catalysts revealed the structure of HT containing the aggregation of nanoparticles. Moreover,
the catalytic activity showed that 20Mn/CHT catalyst provided the target product, N-benzylbenzenesulfonamide,
in 83% yield.
