    • It is worth noting that we tried to "catch" the Bergman product before elimination by closer monitoring of the reaction. 4a was dissolved in DMF with 100 equiv of 1,4-CHD; aliquots were placed into melting point tubes, frozen by liquid nitrogen, degassed under high vacuum, sealed, and placed into an oil bath at 160 °C. Capillaries were withdrawn in different time periods and analyzed by ESI MS. However, only disappearance of 4a (m / z 385) and appearance of 6a (m / z 270) was observed.
