    日期:2010.3.15
    A combination of regioselective room‐temperature/ambient‐pressure hydroformylation (transition‐metal catalysis) and decarboxylative Knoevenagel reactions (organocatalysis) allowed for the development of an efficient, one‐pot C3 homologation of terminal alkenes to (E)‐α,β‐unsaturated acids and esters, (E)‐β,γ‐unsaturated acids, (E)‐α‐cyano acrylic acids, and α,β‐unsaturated nitriles. All reactions proceed
