摘要: A high-yielding sequence of [2+2] cycloaddition-retroelectrocyclization ynamides with tetracyanoethylene (TCNE) is described. The reaction provided tetracyanobutadiene (TCBD) species, which were characterized by various techniques. DFT and TD-DFT calculations also performed to complement experimental findings.
