Subliming organic compounds into a stream of nitrogen gas and passing the vapors rapidly through a very hot oven (flash vacuum pyrolysis) promotes high-temperature thermal reactions in the gas phase that are generally difficult to achieve in solution under ordinary laboratory conditions. Exploring, exposing, and exploiting gas-phase organic chemistry at temperatures of 1000 °C and above has uncovered some extraordinary reactions and led to some landmark syntheses.
