Two accidental nitroalkane reactions reveal complementary photochemical routes to alkenes and unite their discoverers: https://t.co/9edgkayqDY

Check out the article featured in @ChemistryWorld on the photostiching of nitroalkanes. The transformation not only brought two coupling partners together to generate a strong bond, but it also brought two labs together (@ParasramLab and @reiser_group) to form a strong friendship

🔬 This study reports the first direct cross- and self-olefination of nitroalkanes under simple conditions using only a base and visible-light irradiation, providing an efficient route to sterically congested tri- and tetrasubstituted alkenes.

Visible-light irradiation of in situ generated nitronates enabled cross-denitrative olefination through a unique photo-stitching process.

A broad range of functionalized nitroalkanes, including carbonyl- and heterocycle-containing substrates, were well tolerated.

💡 The method provides a practical complement to classical olefination and alkene metathesis for the synthesis of highly substituted alkenes.

Mechanistic studies revealed a photoinitiated radical-chain process in which nitronates act as photoreductants, followed by a photodriven β-elimination.

This work establishes nitronates as versatile photoreductants and coupling partners, opening new opportunities for light-driven radical-mediated olefination.

🐝 We are pleased to see that some nitroalkane substrates used in this study were sourced from AmBeed. In the graphic below, the corresponding 𝗔𝗺𝗕𝗲𝗲𝗱 𝗖𝗮𝘁. 𝗡𝗼𝘀. are highlighted in orange.

Need a method to synthesize tri- or tetrasubstituted alkenes? Check our recent work published in @J_A_C_S on the photo-stitching of nitroalkanes. The transformation proceeds via SRN1–ERC1 mechanism of photogenerated nitronates. @nyuchemistry @NYUScience https://t.co/ycLCzZs2mI
