This review highlights progress made in the last decade in the synthesis of thermally activated delayed fluorescence emitters through C–H bond transformations, and gives an outlook on further challenges and potential directions in this field.
This review summarizes the recent progress in borylation driven by BX3 in the fields of organic synthesis and drug synthesis.
Transition-metal-free C–H functionalization is a long-standing goal in synthetic chemistry. This paper describes a regioselective C(sp3)–H borylation in sp2–sp3 diboranes(5), mediated by a highly reactive B(o-tolyl)2− surrogate.
Herein, we report a Zn/Al catalysed heteroarene C–H borylation using 9-borabicyclo-[3.3.1]-nonane. DFT studies indicated an unusual σ-bond metathesis process between NacNacZn–Aryl and the dimeric hydroborane, involving ligand non-innocence.
This review highlights organoboron-based multiple-resonance compounds’ synthetic strategies classified as one-pot borylation, one-shot borylation, and late-stage functionalisation, and explores material structure–photophysical property correlations.
