Reaction of carbon dioxide with butadiene catalysed by palladium complexes. Synthesis of 2-ethylidenehept-5-en-4-olide

Abstract

The catalytic addition of CO2 to butadiene by Pd-phosphine complexes to yield 2-ethylidenehept-5-en-4-olide was achieved in a polar, aprotic solvent such as dimethylformamide (DMF).
