Introduction

A mild and sustainable synthesis of 2,2-disubstituted oxetanes has been achieved through the use of a flow microreactor system. Oxetane rings have an important role as the main core in naturally occurring compounds as well as versatile motifs both in the total synthesis of natural products [ 1 ] and in synthetic organic chemistry.

The scope of the present study aims at demonstrating the application of 3-D printing technology for catalytic applications. Reaction conditions such as time, reaction temperature, catalyst amount and hydrogen peroxide H 2 O 2 concentration were investigated to fully benchmark the catalytic efficiency in both systems. The conversion and the kinetic data obtained in both systems reveal that the reaction proceeds faster in the flow reactor compared to batch under similar reaction conditions. In addition to enhanced catalytic activity, the stability of both systems was evaluated exemplarily by recycling and reusing recovered catalyst. The microreactor demonstrates an extended service life based on the recyclability studies conducted. Based on these results, the simple, low-cost 3-D printed reactionwares described in this study appears as a promising approach for the oxidation of morin dye in continuous flow.

The application of heterogeneous catalysis in conjunction with microreactor technology can facilitate a cleaner and scalable flow methodology for organic synthesis. In this tutorial review we present recent advances in the design of supported catalysts for emerging synthetic applications within microreactor technology. Specifically, transition metal catalysts such as palladium , copper , ruthenium , and nickel are described on silica , monolithic, magnetic nanoparticles and polymer supports. These catalysts have been utilised to promote a range of reactions including Heck, Sonogashira, Suzuki, Kumada, olefin metathesis , hydrogenation and benzannulation reactions.
