Design, Synthesis, and Photophysical Studies of Functionalized Polyaromatic Isonitriles as Visible Light Photoredox Catalysts

European Journal of Organic Chemistry, EarlyView.
A new series of structurally rich polyaromatic isonitriles is presented as photoredox catalysts. Their photophysical properties are investigated by UV–Vis absorption and fluorescence measurements, combined with experimental and theoretical studies to evaluate both ground‐ and excited‐state redox properties.

Iminodirhodium‐ and Iminocopper‐Catalyzed CH Activation: Chemoselective Oxidation of Alcohols and Aldehydes via Intermolecular Hydride Abstraction

European Journal of Organic Chemistry, EarlyView.
Chemoselective hydride abstractor iminometalloids, derived from O‐mesylacetoxime (MAO) using Rh2(II/II) or Cu(I) catalysts, can activate the C–Hα bonds of alcohols and aldehydes ultimately forming ketones, carboxylic acids, and esters even in the presence of C–H bonds with comparable bond strengths.

Photosensitized cyclodimerization of phenyl vinyl ether

Journal of the Chemical Society, Chemical Communications, 1972
Irradiation of phenyl vinyl ether in the presence of aromatic compounds, such as dimethyl terephthalate, methyl benzoate, or benzonitrile, gives a mixture of trans- and cis-head-to-head cyclodimers of the olefin.
