Application

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

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
