Abstract
A versatile synthetic route to prepare alkyl functionalized 3,5-bis-(2-pyridyl)-1,2,4,6-thiatriazines is described that can proceed either via cationic or anionic pathways; confirmed through characterization of the isolable intermediates. Computational studies are presented, which support the regioselectivity of the alkylation reactions and photophysical properties of the S-alkylated derivatives.
