Ullmann Array Kit

The Copper catalyzed amination kits  is the ideal tools for the investigation of Ullmann reaction conditions. This enables to conveniently screen multiple reaction conditions simultaneously using pre-weighed catalysts and reagents. We offer pre-selected arrays of precatalysts and salts or custom arrays depending on your needs. Key variables Copper Source: CuI Ligands: Phenanthroline, S-Proline, 1,2 cyclohexanediamine, N,N’dimethylethylenediamine, Isobutyrylcyclohexanone Base: K₂CO₃, Cs₂CO₃ and K₃PO₄ Solvent: DMF, DMSO, dioxane or acetonitrile Temperature: 40°C -> 120°C Benefits Facilitates screen of reaction conditions No glove-box needed to manipulate air sensitive or moisture sensitive reagents Enables up to 32 reaction conditions simultaneously Save substrate using low scale reaction conditions Save time on optimization Features 2 ml vial with screw cap and stirring bar. Specifically designed reaction block Pre-weighed reagents and catalysts Temperature from 0°C to 120°C Pre-designed or custom arrays available Reagents are packaged under inert atmosphere Standard Protocol: 50 µmol of substrates in 500 µl solvent (DMF, DMSO, dioxane or acetonitrile, 0.1 mol/L concentration) with 0.1 equivalent of CuI, 0.2 equivalent of  ligand and 1.1 equivalent of base. Kit contents: 2 reaction vials of each catalyst system and base, 36 reaction vials total
