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.
Safety:
GHS05
