The influence of the solvent on the triazolinedione-alkene enereactionmechanism has been investigated. Both inter- and intramolecularkineticisotopeeffects with tetramethylethylenes and 2,2,2-(trideuterio)methyl-7-methyl-2,6-octadiene-[D3]-1,1,1 provide, for the first time, strong evidence for changes in the mechanism of the reaction on going from non-protic to polar protic solvents. In non-protic
