Summary 1. An investigation was made of the condensation of acetylene with cyclopentadiene at high temperature with the object of preparing cycloheptatriene in one stage. At 400–405° with an acetylene pressure of 7 atm we obtained 20% of cycloheptatriene together with 20–25% of 2,5-norbornadiene. 2. A study was made of the effect of the pressure of acetylene on the thermal isomerization of 2,5-norbornadiene into cycloheptatriene, and it was shown that the use of acetylene under pressure diminishes the decomposition of 2,5-norbornadiene into cyclopentadiene and acetylene, as a result of which the yield of cycloheptatriene rises Thus, at 397° increase in pressure from atmospheric to 7.2 atm led to an increase in the yield of cycloheptatriene from 34,8% to 53.5%, calculated on the amount of the norbornadiene that reacted.
