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 considerations strongly suggest that the former and latter reactions proceed through electrophilic substitution reactions with BBr3 and [BBr2·B5]+BBr4-, respectively.

Branching out: Pd-catalyzed iterative triarylations of vinylboronate afford conjugated dendrimers with triarylethene branches (see picture) in a flexible and convergent manner. These highly branched dendrimers reveal good solubility in common organic solvents and exhibit high quantum yields of fluorescence, with the color of the emission ranging from blue to red depending on the extent of branching and hence π conjugation.

(Chemical Equation Presented) A catalytic one-pot triarylation on the C=C core of vinylboronate pinacol ester (1) produces extended π-systems based on a multisubstituted olefin structure very rapidly. We established an efficient protocol for the Pd-cataly
