Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>With regard to sustainability, carbon dioxide (CO₂) is an attractive C1 building block. However, due to thermodynamic restrictions, reactions incorporating CO₂ are relatively limited so far. One of the so‐called "dream reactions" in this field is the catalytic oxidative coupling of CO₂ and ethene and subsequent β‐H elimination to form acrylic acid. This reaction has been studied intensely for decades. However up to this date no suitable catalytic process has been established. Here we show that the catalytic conversion of ethene and CO₂ to acrylate is possible in the presence of a homogeneous nickel catalyst in combination with a "hard" Lewis acid. For the first time, catalytic conversion of CO₂ and ethene to acrylate with turnover numbers (TON) of up to 21 was demonstrated.</p> </abstract>
