摘要
The contributions of Professor Rolf Huisgen to organic chemistry are nu-merous.His research interests mainly focused on the organic reaction mechanism,1,3-dipolar cycloadditions,and orbital control of reactivity,among others.In the early days it was the chemistry of diazo compounds that attracted his interest.His group was able to increase the synthetic possibilities of this chemistry and to broaden the mechanistic knowledge about the reactions of diazo-and diazonium compounds.The reactions of N-nitrosoacylamides were studied in depth leading to formulation of al-kanediazonium ion pairs and the subsequent formation of carbocations in various product forming steps.
