Abstract: Chromophores incorporating enaminone units were efficiently synthesized using click‐type [2+2] cycloaddition‐retroelectrocyclization (CA‐RE) reactions. The preparation of electron‐rich alkynes necessary for these reactions initiated with the synthesis of alkynones via Sonogashira cross‐coupling, followed by nucleophilic conjugate… read more here.

Abstract: Donor-acceptor-substituted alkynes, endowed with 11,11,12,12-tetracyano-9,10-anthraquinodimethane (TCAQ) and N,N-dimethylaniline (DMA) units, have been further functionalized by a [2+2] cycloaddition with tetracyanoethylene (TCNE) followed by a subsequent retro-electrocyclization to form distorted nonplanar structures with bridging 1,1,4,4-tetracyanobuta-1,3-diene (TCBD)… read more here.
