Applicazioni

Di-tert-butyl(methyl)phosphonium tetrafluoroborate may be used in the preparation of a precursor for nantenine analogs bearing a C4 phenyl substituent, which shows an affinity for 5-HT2B receptor. It may also be used in the palladium-catalyzed borylation of primary alkyl electrophiles (bromides, iodides or tosylates) using bis(pinacolato)diboron or bis(neopentyl glycolato)diboron as the boron source.
The phosphonium salt is used for Pd catalyzed cross coupling reaction.

A general and efficient synthesis of 5-aryl imidazo[1,5- a]pyrazines by palladium-catalyzed coupling of the corresponding 8-substituted derivatives with aryl halides is described. The scope of this new reaction for the imidazo[1,5- a]pyrazine ring system was explored using three readily available

Direct arylation reactions of nitrobenzenes and aryl halides occur in good yield and high ortho regioselectivity. These reactions can be performed on gram scale with as few as 3 equiv of the nitro arene relative to the aryl halide. The

Penta-, tetra-, tri-, and difluorobenzenes undergo direct arylation with a wide range of arylhalides in high yield. Inverse reactivity is observed compared to the common electrophilic aromatic substitution pathway since electron-deficient, C-H acidic arenes react preferentially. Computational studies indicate that
