Synthesis of (E)-1,2-Divinyl-1,2-diethynylethene (DVDEE) via the Palladium-Catalyzed Reaction of Conjugated Diynes. A New Building Block for Molecular Scaffolding
journal contribution
posted on 2002-01-19, 00:00 authored by Drexel H. Camacho, Shinichi Saito, Yoshinori YamamotoConjugated diynes undergo dimerization in the presence of acetic acid and catalytic amounts of Pd(PPh3)4. The unprecedented reaction gives a novel chromophore containing the (E)-1,2-divinyl-1.2-diethynylethene (DVDEE) module, which is a potentially viable building block for acetylenic scaffolding.
