(-)-灏?Pinene-based 鐣?sup>3-锜?allylpalladium complex was shown the efficacy in the catalytic asym. allylation of para- and meta-xylene spaced bis-arylimines. The complex was catalyzed asym. allylation of various bis-imines in the presence of allyltributylstannane and two equivalent of water furnished chiral bis-homoallylamines in moderate to good yields (up to 70%) and enantioselectivities up to 98.6 : 1.4 er. In the experiment, the researchers used many compounds, for example, Isopentyltriphenylphosphonium bromide (cas: 28322-40-9Formula: C23H26BrP).
Isopentyltriphenylphosphonium bromide (cas: 28322-40-9) belongs to organobromine compounds. Bromo compounds are employed in a variety of metal-catalyzed coupling reactions. They are also ideal candidates for the synthesis of Grignard reagents that have wide-applicability in organic synthesis. alpha-Bromoesters are employed in the Reformatsky reaction for the synthesis of beta-hydroxyesters. The reactivity of organobromine compounds resembles but is intermediate between the reactivity of organochlorine and organoiodine compounds. For many applications, organobromides represent a compromise of reactivity and cost.Formula: C23H26BrP
