## Abstract The many fold aromatic ketones **2a‐d** are versatile compounds for the synthesis of the many fold 1,2,3‐selenadiazole aromatic derivatives **5a‐d**. The preparation starts with the reaction between the many fold bromomethylene benzene derivatives **1a‐d** and 4‐hydroxyacetophenone, whi
## Abstract Chemical shifts are reported for the heterocyclic ring hydrogen of a series of __para__‐substituted 4‐aryl‐1,2,3‐selenadiazoles and substituent effects are evaluated statistically by means of the Swain‐Lupton multiple correlation analysis. A satisfactory understanding of the various sub
## Abstract The ^13^C, ^15^N and ^77^Se NMR data (chemical shifts and coupling constants) of some cycloakeno‐1,2,3‐selenadiazoles are presented. Extremely large ^77^Se chemical shifts are found. ^15^N, ^77^Se coupling constants, obtained at natural abundance, are reported for the first time. Strong
