Mild Generation of Highly Nucleophilic N‐Heterocyclic Carbene Boryl Anion From Neutral sp2–sp3 Diboron Reagents and Its Applications in Nucleophilic Borylation

Angewandte Chemie, EarlyView.
A less hindered and highly nucleophilic N‐heterocyclic carbene (NHC) boryl anion is generated at room temperature by reacting sp2–sp3 diboron reagent (NHC)BH2Bpin with KOtBu. This highly reactive anion demonstrates broad reactivity with various electrophiles, including those traditionally considered inert, enabling their efficient borylation.

Arylhydrazines: Convenient Homogeneous Reductants for Scalable Cross‐Coupling

Angewandte Chemie, EarlyView.
Reductive cross‐couplings enable efficient C–C bond formation but are limited by the heterogeneity of Zn or costly reagents like TDAE. We report arylhydrazines as inexpensive, convenient reductants for Ni‐catalyzed sp2–sp3 coupling of aryl halides and secondary alkyl iodides. Mechanistic studies support hydrazine‐mediated NiII reduction for a NiI/NiIII

Stable BF2 Boracycles as Versatile Reagents for Selective Ortho C–H Functionalization

Angewandte Chemie International Edition, EarlyView.
We report a robust, metal‐free and scalable synthesis of stable BF2 boracycles via directed ortho CH borylation, delivering isolable, shelf‐stable reagents without chromatographic purification. These BF2 boracycles exhibit unique and tunable reactivity, enabling highly selective ipso‐functionalization across a broad range of transformations.

Experimental Isolation of Single Impact, Cumulative Energy, Aging, and Liquid‐Assisted Grinding Effects in Mechanochemical Reactions

Angewandte Chemie International Edition, EarlyView.
An experimental framework is introduced to isolate single‐impact and cumulative energy within a mechanochemical system. The guided, stepwise approach highlights the fundamental roles of impact events, post‐impact reactivity, and liquid‐assisted grinding additives in all‐solid mechanochemical reactions.
