Synthesis of the Butatriene C4 Function Methodology and Applications

C2nH2n hydrocarbons are the first representatives of thecategory of the so-called “carbon-rich” molecules (C/H g 1).1The electronic strain of small C2nH2n species with filled valenceshells (n + 1 unsaturations or cycles over n connected carbonatoms) makes the corresponding C2n skeletons a priori reactiveall-carbon functions, which are valuable for bot..
