Exploring Homogeneous Conditions for Mild Buchwald-Hartwig Amination in Batch and Flow

We describe the use of high throughput experimentation to identify a number of conditions that enable Buchwald-Hartwig reactions to be carried out using readily available ligands (e.g. XantPhos) with DBU as a soluble, functional group tolerant, homogeneous base. Application of this system to diverse aminations in batch and flow are demonstrated, as is the translation of this technique to performing continuous Mizoroki-Heck and Sonogashira coupling reac-tions.
