The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.224311-51-7, Name is 2-(Di-tert-Butylphosphino)biphenyl, molecular formula is C20H27P.

The trans bromide of 2,2-dibromo-1-(2,4,6-tri-t-butylphenyl)-1-phosphaethene (Mes*P=CBr2; Mes=2,4,6-tBu3C6H2) can be successfully substituted with an aryl group by using a palladium version of the Kumada-Tamao-Corriu cross-coupling process. Predominant formation of the 2-aryl-2-bromo-1-phosphaethene [(Z)-Mes*P=C(Br)Ar] required suitable conditions including optimization of the ancillary phosphine ligand, thereby retarding the dual elimination of bromides leading to phosphaalkyne (Mes*C?P). The 2-aryl-2-bromo-1-phosphaethenes hold promise as versatile synthons for functional pi-conjugated molecules, and stereospecific transformations of the bromine atom by halogen-metal exchange and palladium-catalyzed arylations were demonstrated.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Quality Control of: 2-(Di-tert-Butylphosphino)biphenyl, you can also check out more blogs about224311-51-7
