When diazoketones 3a and 3b are pyrolysed at 43oOC and 10S4 torr, they undergo loss of N2 followed by Wolff rearrangement and loss of furan by retro Diels-Alder reaction to yield the desired propadienones l(a.b). If argon is added to the pyrolysate mixture, these reactive compounds can be trapped un
