    • Flash Vacuum Pyrolysis of 8a-j The sample was volatilized from a tube in a Buchi Kugelrohr oven through a 30 x 2.5 cm horizontal-fused quartz tube and was heated externally by a cabolite Eurotherm tube furnace MTF-12/38A to 600°C. The products were collected in a U-shaped trap cooled in liquid nitrogen. The whole system was maintained at a pressure of 10-2 Torr by an Edwards Model E2M5 high-capacity rotary oil pump, the pressure being measured by a Pirani gauge situated between the cold trap and pump. Under these condition the contact time in the hot zone was estimated to be 10 ms. Products collected in the U-shaped trap were analyzed by 1H NMR, 13C NMR, IR and GC-MS. Relative and percent yields were determined from NMR. Compounds 11a,c,d,f-h,j-n, 16, and 17 has been reported earlier and proved to be identical with products obtained here.19-27
