Lit Reviews: Decarboxylative Alkylation of Alkenes

In this video, we break down a 2026 Nature paper from Tobias Ritter’s group reporting a new decarboxylative alkylation of alkenes using carboxylic acids as alkyl sources. This method tackles a longstanding challenge in organic chemistry: directly converting simple alkenes into more substituted alkenes without relying on traditional indirect strategies like Wittig, HWE, Julia olefination, or cross-metathesis. The key advance is a polar decarboxylative pathway in which redox-active esters are reduced by zinc in N,N-dimethylformamide (DMF) to form an unexpected alkylzinc intermediate, which then undergoes palladium-catalyzed cross-coupling with alkenyl thianthrenium salts. We cover the reaction design, mechanism, scope, stereochemical control, mechanistic evidence, limitations, and why this work could reshape retrosynthetic thinking in alkene functionalization, decarboxylative cross-coupling, and the synthesis of highly substituted alkenes. If you’re interested in organic chemistry, reaction mechanisms, cross-coupling, medicinal chemistry, chemical synthesis, and new developments in the chemistry literature, this paper is an important one to know.
