Amine–borane complex-initiated SF5Cl radical addition on alkenes and alkynes

“…Compared to trialkylboranes, amine–borane complexes have shown to be more stable [ 38 ]. Indeed, they are usually air-stable, and their preparation from NaBH 4 , H 2 SO 4 and amines involves traditional mild acidic work-up without degradation.…”

Complete deconstruction of SF6 by an aluminium(i) compound

“… 55–59 2 also reacted with BCl 3 to produce a series of commercially relevant Lewis acids. 60,61 Finally, despite its lack of solubility, we were able to demonstrate the transfer of sulfide (S 2− ) from 3 to α,α′-dibromo- o -xylene to form the sulfur heterocycle 4 ( Fig. 3 ).…”

H5BW12O40as a green and efficient homogeneous but recyclable catalyst in the synthesis of 4H‐Pyransviamulticomponent reaction

“…Boron trifluoride is most typically used as Lewis acid catalyst in several organic reactions . Examples include: as initiator in polymerisation reactions of unsaturated compounds, such as polyethers and some other polymerization, isomerization, acylation, alkylation, esterification, dehydration, condensation, Mukaiyama aldol addition and etc .…”
