1,4-Dihydropyridines as Alkyl Radical Precursors: Introducing the Aldehyde Feedstock to Nickel/Photoredox Dual Catalysis

A Ni/photoredox dual catalytic cross-coupling is disclosed in which a diverse range of (hetero)aryl bromides are used as electrophiles, with 1,4-dihydropyridines serving as precursors to Csp3-centered alkyl radical coupling partners. The reported method is characterized by its extremely mild reaction conditions, enabling access to underexplored cores.

Two different models that calculate association constants from UV–vis titration data have been evaluated for the 1:1 binding between triazolophane receptor ([Host] 1⁄4 1–13mM) and various halides F, Cl, Br and I in CH2Cl2 (Ka < 10–10 M). The Drago model fits the DA values at a single wavelength as a function of the added guest concentration. The new computer program Sivvu performs equilibrium-r...
