Tri-tert-butylphosphine(Cas 13716-12-6) Usage


Useful as a ligand in a variety of palladium-catalyzed C-N, C-O and C-C bond-forming reactions under mild conditions.

Chemical Properties

Colorless to light yellow liqui


Tri‐tert‐butylphosphine (P t Bu3) is used as a ligand in transition metal catalysis, from common palladium‐promoted cross coupling reactions 1 to less usual copper‐catalysed [3 + 2] cycloaddition of cyclic ketones to olefins or alkynes.
