for the Sonogashira cross-coupling exploiting the safe use of a CPME/water azeotropic mixture and the utilization of a heterogeneous hybrid palladium catalyst supported onto a silica/β-cyclodextrin matrix in continuousflow. The use of the aq CPME azeotrope has proven to be crucial to enhance the catalyst performance including very low metal leaching. In addition, we have also completed the flow protocol
