✦ Synopsis

A fundamental mechanistic ambiguity in the thermal conversion of cyclopentene to cyclopentadiene and hydrogen has been recognized but unreeolved for over twenty years (l-3): Are the hydrogen atoms which become molecular hydrogen in a 1,4or a 1,2-relationship in cyclopentene? Does the reaction occur through a 6-centered or a b-centered transition state?
