摘要：

For a simple biphasic hydrolysis, we show that the application of various reaction conditions in microreactors using segmented flow can dramatically increase the reaction rate. A tandem diazotation/Heck reaction served as an example that even homogeneous reactions can be accelerated by segmentation in microreactors.
