Article abstract of DOI:10.1021/jo00379a015

A series of highly hindered ortho-alkylated azobenzenes has been isolated in the cis configuration for the first time.The crystal structure of one of these compounds, cis-2,2',6,6'-tetraisopropylazobenzene, shows that the molecule accommodates the bulky s
