Abstract: This study investigated the microstructures of polymers produced via photoredox-mediated metal-free ring-opening metathesis polymerization. Polynorbornene, poly(exo-dihydrodicyclopentadiene), and poly(endo-dicyclopentadiene) were found to have cis olefin contents of 23%, 24%, and 28%, respectively. Additionally, the cis/trans ratio… read more here.

DOI: 10.1021/acscatal.8b02954
Abstract: Medicinally relevant diarylamines are prepared through a photoredox-mediated dual catalytic nickel/ruthenium system from aryl azides and aryl electrophiles. Photoreduction of the aryl azide is proposed to proceed through an arylnickel-azide complex, which upon reduction and… read more here.
