Temperatures can exceed 900 °C when a strongly microwave‐conducting thin‐metal film is irradiated. In the Full Paper by M. G. Organ and C.‐J. Li et al. on page 126 ff., Au and Cu films have been shown to be very proficient at catalysing the three‐component coupling of terminal alkynes, amines, and aldehydes to produce propargyl amines.
An effective multi‐component reaction (MCR) protocol has been developed for the construction of propargyl amines from aldehydes, amines and terminal alkynes by using microwave‐assisted continuous‐flow organic synthesis (MACOS). The process is catalysed by thin films of either copper or gold that achieve temperatures in excess of 900 °C when irradiated with low levels of microwave power. The process...
