General description

CPhos Pd G3 is a modified G3 precatalyst (G3′). It has been synthesized by Buchwald and coworkers from second generation (G2) precatalyst by methylation of the amino group present on biphenyl backbone. It is a useful catalyst for various cross-coupling reactions. They are versatile catalysts. They have long life in solution and are readily soluble in various organic solvents. G3- precatalysts have been employed in various C-N bond forming reactions.

KitAlysis™ 高通量筛选试剂盒扩容指南

所有固体(碱、底物、催化剂)均需在试验台天平上称重,并添加至(烘箱)干燥的冷却烧瓶中1,2,烧瓶中置入一个经烘箱干燥的搅拌棒。将反应体系加盖,并使用多道氮气针通入氮气进行3次吹扫和充填。之后使用注射器加入无水溶剂(经SureSeal™处理,使用多道氮气针刺入)。如需液态碱,液态碱将作为最终成分通过注射器加入。加入各种成份时,需移去氮气管线3 ,使整个反应过程在指定温度下一直处于搅拌状态。
