The synthesis of a diverse range of heterobiaryl has been achieved via a transition metal free sp 2 -sp 2 cross coupling strategy using lithiated heterocycle, aryl or heteroaryl boronic ester and an electrophilic halogen source. The construction of heterobiaryls was carried out through electrophilic activation of the aryl-heteroaryl boronate complex which triggered 1,2-migration from boron to the carbon atom. Subsequent oxidation of the intermediate boronic ester afforded heterobiaryls in good…

TLDR
A novel radical-mediated annulation provides polycyclic products with high enantio- and diastereoselectivity in the specific case of methyl-vinyl ketone as well as a stepwise allylation-aryl/alkyl migration.
Direct catalytic cross-coupling of organolithium compounds
TLDR
A general and selective palladium-catalysed cross-coupling of aryl- and alkenyl-bromides with a wide range of alkyl-, aryL- and heteroaryl-lithium reagents is reported, which avoids the notorious lithium–halogen exchange and homocoupling side-reactions commonly associated with these extremely reactive organometallic compounds.

TLDR
A new approach that uses a single organic sulfide catalyst to activate both C(sp3) halides and arylboronic acids via a zwitterionic boron "ate" intermediate is described, demonstrating orthogonal chemoselectivity in the streamlined synthesis of highly functionalized diaryl methane scaffolds using multi-halogenated substrates.
Development of Enantiospecific Coupling of Secondary and Tertiary Boronic Esters with Aromatic Compounds
TLDR
This work reasoned that subsequent addition of an oxidant or an electrophile would remove an electron from the aromatic ring or react in a Friedel–Crafts-type manner, respectively, generating a cationic species, which would trigger 1,2-migration of the boron substituent, creating the new C–C bond.

TLDR
It is demonstrated that vinyl boronic ester ate complexes, prepared by combining organoboronates and organolithium reagents, engage in palladium-induced metallate rearrangement wherein 1,2-migration of an alkyl or aryl group from boron to the vinyl α-carbon occurs concomitantly with C–Pd σ-bond formation.
