Reactions between various benzyl alcohols or tert-butyl alcohol and nitriles were carried out in the presence of catalytic amounts (usually 10–20 mol-%) of o-benzenedisulfonimide as a Bronsted acid catalyst; the reaction conditions were mild and the yields of amides were good. The catalyst was easily recovered and purified, ready to be used in further reactions, with economic and ecological advantages
各种苯甲醇或叔丁醇与腈之间的反应是在催化量(通常为 10-20 mol%)的邻苯二磺酰亚胺作为布朗斯台德酸催化剂存在下进行的。反应条件温和,酰胺收率良好。该催化剂易于回收和纯化,可用于进一步的反应,具有经济和生态优势。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
