Di-t-butylmethylphosphonium tetrafluoroborate, 99%

Technical Note:
1.Air and moisture-stable phosphonium salt used in palladium-catalyzed coupling reactions. The phosphoniumsaltis s deprotonated in situ to yield the free phosphine ligand. Use of the phosphonium salt furnished nearly identical product as reactions carried out using the phosphine.
2. Ligand for the Pd-catalyzed heteroaromatic direct arylation.
