Pressurized microreactor systems greatly expand the range of reaction conditions and accelerate gas–liquid mass transfer. Heck aminocarbonylation reactions exemplify the potential for the quick and safe scanning of reagents and reaction conditions. The yield of amide increases with an increase in temperature and the selectivity for α-ketoamide production (n=2) increases at lower temperature and higher pressure.
