The conversion of olefin feedstocks to architecturally complex alkanes represents an important strategy in the expedient generation of valuable molecules for the chemical and life sciences. Synthetic approaches are reliant on the electrophilic activa

Herein we report the photophysical and photochemical properties of palladacycle complexes derived from 8-aminoquinoline ligands, commonly used auxiliaries in C–H activation. Spectroscopic, electrochemical and computational studies reveal that visib

We report the discovery of a tandem catalytic process to reduce energy demanding substrates, using the [Ir(ppy)2(dtb-bpy)]+ (1+) photocatalyst. The immediate products of photoinitiated electron transfer (PET) between 1+ and triethylamine (TEA) underg

Herein we report a visible light multiphoton tandem photoredox catalysis strategy enabling a distinctive mode of olefin activation via a one electron reduction to the corresponding radical anion. This highly nucleophilic intermediate was harnessed to

The Ru(II)-catalyzed amidation of 2-arylpyridines with aryl isocyanates via C-H bond activation is less efficient than described previously, due to the formation of a series of side products, which were readily identified using direct infusion electr

The general catalytic synthesis of aryl and vinyl thioethers from readily available halides remains a challenge. Herein we report a unified method for the thiolation of aryl and vinyl iodides with dialkyl disulfides using visible light photoredox cat

Herein we describe the auxiliary-directed arylation of unactivated C(sp3 )-H bonds with aryldiazonium salts, which proceeds under synergistic photoredox and palladium catalysis. The site-selective arylation of aliphatic amides with α-quaternary cent

A methodology for a radical Pictet–Spengler reaction promoted by visible light photoredox catalysis is described. This strategy furnishes tetrahydroisoquinoline derivatives bearing electron poor and electron rich substituents. The reaction proceeds
