Abstract: An operationally simple nucleophilic trifluoromethoxylation protocol via an inexpensive, commercially available and bench stable reagent, carbonyl diimidazole and AgF is presented. Mechanistic studies are performed to reveal that this method does not proceed through the… read more here.

Abstract: Mn-mediated reductive cross-coupling of organic bromides with 2-bromo-1,3,2-diazaphospholene was developed for efficient construction of C-P bonds under mild conditions. Mechanistic studies suggested that bromides are activated by in situ formed bis-diazaphospholene via hybrid radical and… read more here.
