Abstract: We report a photoredox platform for constructing styrenyl polyfluoro (hetero)arenes with branch selectivity by taking advantage of sulfinate as both a radical-relay precursor and a sacrificial nucleofuge. This protocol merges photoredox catalysis with radical-radical coupling… read more here.

DOI: 10.1021/acscatal.9b05137
Abstract: We report here a Ni-catalyzed reductive coupling of aldehydes with widely available 1,3-dienes under visible-light photoredox dual catalysis. The homoallyic alcohols are obtained in broad scope with complete branched regioselectivity. Hantzsch ester is used as… read more here.

DOI: 10.1021/jacs.2c07477
Abstract: Catalytic branch-selective hydrofunctionalization of feedstock α-olefins to form enantioenriched chiral compounds is a particularly attractive yet challenging transformation in asymmetric catalysis. Herein we report an iridium-catalyzed asymmetric hydroalkenylation of α-olefins through directed C-H cleavage of… read more here.
