Abstract: A variety of terminal alkenes, as well as heteroaromatic compounds, are borylated by the combined use of BBr3/2,6-dichloropyridine (B3) or BBr3/2,6-lutidine (B5). α,α-Diarylalkenes prefer the former reagent combination, while other alkenes prefer the latter. Mechanistic… read more here.

DOI: 10.1021/jacs.9b04665
Abstract: We present the first quadruple borylation reaction of terminal alkynes, affording functionalized 1,1,2,2-tetrakis(boronate) derivatives in a chemo-/regioselective manner. The methodology is operationally simple and a novel B-B bond activation without the need for a transition-metal… read more here.
