allowing higher productivities and space–time yields compared with gas-phase protocols. Differential scanning calorimetry measurements and extensive DFT calculations provided essential information on pyrolysis energy barriers and the involved reaction mechanisms. A correlation between computed activation energies and experimental gas-phase FVP (molecule–wall collisions) and liquid-phase FFP (molecule–molecule

Acylaminomethylene Meldrum'sacidderivatives 5 are prepared either by direct reaction of methoxymethylene Meldrum'sacid 4 with primary amides, or by acylation of aminomethyleneMeldrum'sacid 6. Pyrolysis of the substrates 5 under FVP conditions gives the title compounds 8 in good yields.
