The configuration and conformation of aryl diazotates and diazocyanides

Abstract 15 N and 13 C NMR parameters and 4-substituent effects reflect the configuration and conformation in solution of 15 N-labelled syn -(Z)- and ant -(E)- aryl diazotates ArNNO − and aryldiazocyanidas ArNNCN, as for other aryldiazo compounds.
