Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 97239-80-0, C22H28FeP2.

Palladium 1,1?-bis(diisopropylphosphino)-ferrocene [Pd(dippf)] complexes were found to promote the monoarylation of primary anilines with unprecedented selectivities. They also allow the sequential arylation of primary anilines with two different aryl bromides in one pot. The reactions can be performed at low catalyst loadings (0.2 mol%) and high substrate concentrations. The synthetic utility of the optimum catalyst was demonstrated by the synthesis of various di- and triarylamines. A particular focus was set on compounds with carbazole and fluorene moieties as employed in state-of-the-art small-molecule organic light emitting diodes (OLEDs). (Figure presented.).
