Phosphorane ylides and phosphonate anions react smoothly with resin-bound aldehydes and ketones to provide alkenes in good yields and purities (assessed after cleavage of acid-labile PAL anchor to support). The reactions of aldehydes give excellent stereoselectivities. Effective conditions have been developed for carrying out these transformations.

AbstractAldehydes and ketones are widely found in biomass resources and play important roles in organic synthesis. However, the direct deoxygenative coupling of aldehydes or ketones to construct C(sp3)−C(sp3) bond remains a scientific challenge. Here we report a nickel−catalyzed reductive homo-coupling of moisture- and air-stable hydrazones generated in-situ from naturally abundant aldehydes and ketones to construct challenging C(sp3)−C(sp3) bond. This transformation has great functional group compatibility and can suit a broad substrate scope with innocuous H2O, N2 and H2 as the by-products. Furthermore, the application in several biological molecules and the transformation of PEEK model demonstrate the generality, practicability, and applicability of this novel methodology.
