We report acylation of alcohols and amines employing acetic acid as an acylating agent in solvent free condition by using alum doped nanopolyaniline (NDPANI) as a catalyst. This environmentally benign method does not use corrosive acid anhydrides and acid chlorides for acylation and does not produce waste product. Also, a non-toxic potash alum was used for doping of polyaniline rather than corrosive acids. The reaction conditions represent an advance over established method not only in omitting the need for expensive catalysts or solvents but also in shortening the reaction time significantly. The advantages of this catalyst are non-hazardous, cheap, reusable, easy to prepare and handling.

明矾掺杂纳米聚苯胺在无溶剂条件下高效、经济、环保地酰化醇和胺
我们报告了在无溶剂条件下，通过使用掺铝纳米聚苯胺 (NDPANI) 作为催化剂，使用乙酸作为酰化剂的醇和胺的酰化。这种环境友好的方法不使用腐蚀性酸酐和酰氯进行酰化，也不产生废品。此外，无毒的钾明矾用于掺杂聚苯胺而不是腐蚀性酸。反应条件比既定方法更先进，不仅无需昂贵的催化剂或溶剂，而且显着缩短了反应时间。这种催化剂的优点是无害、便宜、可重复使用、易于制备和处理。
