Decoding Transmetalation in Miyaura Borylation: The Hidden Chemistry of Bis(pinacolato) Diboron and Base Effects

Advanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.
DFT analysis of the Pd(IMesMe)(cin)Cl precatalyst in Miyaura borylation of aryl chlorides clarifies key mechanistic steps. The second base equivalent directly participates, while B2Pin2 activation involves Pd coordination rather than independent cleavage.

Asymmetric remote C-H borylation of internal alkenes via alkene isomerization

Nature Communications, 2018
Sequential alkene isomerization/functionalization enables enantioselective transformations of remote C–H bonds. Here, the authors report a chiral cobalt catalytic system for the highly enantioselective, remote C–H borylation of internal alkenes via an ...

Persistent Boryl Radicals as Highly Reducing Photoredox Catalysts for Debrominative Borylations

Journal of the American Chemical Society
Organic free radicals are commonly perceived to be highly reactive species with short lifetimes, yet there are many examples that defy this convention by displaying remarkable stability. Although these persistent radicals can be relatively unreactive in their ground states, photoexcitation can generate highly reactive excited states. Despite this, they
