KitAlysis™ C-N (Buchwald-Hartwig) High-Throughput Screening Kit

• Cesium Carbonate: ground and sieved in 2 pre-weighed vials with product labels and lids
  
• 2 empty reaction vials with lids

All contents in the foil bag are weighed, plated, packed, and sealed in a glove box under nitrogen.

Ampule Boxes:

• Dioxane: 10 x 2 mL of degassed, anhydrous Sure/Seal™
• DMAc: 10 x 2 mL of degassed, anhydrous Sure/Seal™
• NaOt-Bu Solution: 4 x 0.5 mL degassed anhydrous Sure/Seal™ 2 M THF solution

Internal Standard:

• Biphenyl (30 mg). To be added to the reaction during the work-up. Recipe for the work-up with the internal standard can be found within the hyperlinked screen types in the "Kit Design" section below.

Kit Design

C-N (Buchwald-Hartwig) cross-coupling kit was designed to provide the best possible chance of success and is run with:

• 10 µmol aryl halide
• 15-20 µmol amine (primary, secondary), use 20 µmol if the material is not too precious
• 1 µmol catalyst per vial (1:1 Pd:Ligand); 12 in this system
• 30 µmol base (NaOt-Bu or Cs₂Co₃)
• 0.1 M solvent concentration (Dioxane or DMAc)

The C-N (Buchwald-Hartwig) cross-coupling kit allows the end user ultimate control and flexibility based upon their specific chemical system. For each kit, there are four possible screens that can be run based upon the substrates you provide:

• Two Solvents, Weak Base (Cs₂CO₃)
• Two Solvents, Strong Base (NaOt-Bu)
• One Solvent (Dioxane), Two Bases
• One Solvent (DMAc), Two Bases

The following guidelines can be used to determine your starting point:

The kit was purposefully designed to be modular, meaning that you can run 4 different kits, 4 identical kits, one of each, or any combination. All of the supplies can be mixed and matched to meet your needs.

Step-by-step user guide and an excel sheet for stock solution recipes that can be downloaded within each step-by-step user guide hyperlinked above.

Use of the Provided Tools

Multiple tools have been created to ensure your success with kit set up. Start with the more detailed guide to ensure you are comfortable with all of the steps before using the quick guides on the excel worksheet. Remember that while the technique is new, it is still organic chemistry and so the steps will seem easy once you try just one kit. It is just a new way of approaching something you are already very good at.

Detailed Set-Up User Guide:

Designed for the first time user and should be read completely before getting started. Best if used in conjunction with the video as not all steps are outlined in the video in great detail. This guide includes trouble-shooting tips, how-to’s for the Labware, and work-up recipes with procedures. Everything you need to set up a kit with confidence every time.

Excel Sheet:

Each sheet is designed to be used with the specific experimental design chosen by you depending upon the attributes of your substrates. The downloadable excel files are specific to the kit being run and can be found within each Step-by-Step User Guide. They have the following features:

• Calculations for substrate recipies depending upon the molecular weight of your substrates
• Quick directions for the more avid user
• Print button to allow you to take recipe to the lab
• Contain all info such that they can be can be saved as a pdf and appended to ELN for experimental information
