Buchwald Cross Coupling Array:
Pd Catalyzed Amination Kit 2
2 sets of 24 reagent combinations premixed in same vial; 8 Catalysts (BrettPhosG2, RuPhosG2, XPhosG2, tBuXPhosG3, tBuBrettG3, Pd2dba3/
This kit requires EvoluChem™ reaction block (HCK1006-01-002) included in the EvoluChem™ Starter Kit (HCK1006-01-001)
The typical protocol is performed at 0.15 mol/l concentration reaction condition and 1 to 1 ratio substrates in 100 µl selected solvent. Resulting catalyst loading is 10%. Two equivalents of base are preloaded (30 µmol). It is possible to decrease substrate concentration by increasing the reaction volume (see chart below). Maximum volume for reaction condition is 250 µl. Recommended solvents are tBuOH or Toluene.
Protocol at 100 µl volume reaction condition
requiredvolume of a 0.15 mol/L solution of combined substrates in the desired sparged solvent. For example, 2500 µl solution for 24 reaction conditions (100 µl extra to compensate potential evaporation).
- Using a clean and dry syringe, add 100 µl of substrates solution to each reaction vial.
- Stir the reaction vials in the reaction block at
desiredtemperature (for example:80°C) for 3 to 12 hours.
- Remove the vial caps using a
analyticalsample for each reaction condition with 5 µl sample diluted into 200 µl in either DMSO or water/acetonitrile 50/50.
Analyze resulting analytical samples by LC/MS.
