Preparation, Structure Determination, and Electrochemical Properties of 4,5-Dialkylbenzo[1,2-d:4,5-d’]bis[1,2,3] triselenoles and Their Singlet and Triplet-State Dications

摘要

4,8-Dialkylbenzo[1,2-d:4,5-d’]bis[1,2,3]triselenoles [alkyl=Et, Bu, and Oc (C8H17)] were first prepared and treated with concen- trated sulfuric acid-d2 to generate benzobistriselenole dications, which were determined by NMR spectroscopy. The oxidation of dioctylbenzobistriselenole with three equivalents of single- electron oxidizing reagent (NOSbF6) produced the correspond- ing dication* 2SbF6-and the salt was isolated into a stable form.
