When diazoketones 3a and 3b are pyrolysed at 430°C and 10-4 torr, they undergo loss of N2 followed by Wolff rearrangement and loss of furan by retro Diels-Alder reaction to yield the desired propadienones 1(a,b). If argon is added to the pyrolysate mixture, these reactive compounds can be trapped under matrix isolation conditions at 22 K and observed by FTIR. Upon photolysis, 1b yields carbon monoxide and 2-butyne.
