The synthesis and characterization of four new tetracyanobutadiene (TCBD) derivatives (1,3cand4b-c) incorporating tosylamido and 4-triphenylamino moieties are reported. Along with those of five closely related or differently branched TCBDs derivatives (2,

A high-yielding sequence of [2+2] cycloaddition-retroelectrocyclization of ynamides with tetracyanoethylene (TCNE) is described. The reaction provided tetracyanobutadiene (TCBD) species, which were characterized by various techniques. DFT and TD-DFT calculations were also performed to complement experimental findings. 2+2=Tetracyanobutadienes: The reaction between ynamides and tetracyanoethylene at room temperature in dichloromethane provides tetracyanobutadienes in good to quantitative yields, following a sequence of [2+2] cycloaddition-retroelectrocyclization (see scheme; EWG=electron- withdrawing group).
