Description and Uses

Tri-tert-butylphosphonium Tetrafluoroborate is used in the synthesis of substituted biaryl compounds via palladium catalyzed tandem Heck-direct arylation and tandem- sequential Heck-direct arylation-hydrogenation. Also used in the synthesis of a novel organic dye with fluorenone as conjugation bridge which is used in dye sensitized solar cells.
