Herein, we present a nickel-catalyzed C–S cross-coupling between aryl halides and ketene dithioacetals under "base-free" conditions without an exogenous ligand. By employing easily available as sulfide donors, this reaction affords broad range of unsymmetrical alkyl-aryl sulfides using odorous toxic thiols. The newly developed catalytic methodology features excellent functional group tolerance, wide substrate scope, diverse downstream synthesis. Preliminary mechanism investigations reveal that Ni(I)/Ni(III) cycle might be involved.

Thioesters are important in synthesis, materials science, and biology, their preparation traditionally relies on the use of disagreeable thiols. Here, we report a thiol-free protocol that stitches together widespread carboxylic acids aryl halides, producing diverse array thioesters. Crucial to this strategy is discovery tetramethylthiourea can serve as both sulfur source and, upon direct excitation by purple light, strong reductant, suitable for activating halides via single-electron transfer. Coupling resulting radicals provides an isothiouronium ion intermediate, which be attacked polar pathway, affording thioester products under mild conditions.

p-Diarylboryl halothiophenols are developed and unequivocally characterized. Their photophysical properties catalytic performance unveiled by experimental theoretical investigations. This novel class of triarylboranes behaves as a Brønsted acid to generate the corresponding borylthiophenolate that can absorb visible light undergo intramolecular charge transfer form radical pair consisting boron anion thiyl radical, which acts single-electron reductant while engaging in hydrogen atom regenerate parent borylthiophenol. The synthetic relevance this mode action is demonstrated establishment unique catalysis integrates three different yet tunable functions single cycle, thereby allowing borylthiophenols solely promote assembly sterically congested 1,2-diols 1,2-aminoalcohol derivatives via radical–radical cross-coupling.
