## Abstract The pyrolysis of ethyleneβbuteneβ2 mixtures has been studied in a static system over the temperature range of 689Β°β754Β°k and for initial pressures of each olefin of 20β200 torr. The two main addition products were cyclopentene and 3βmethylpenteneβ1. Kinetic evidence indicated that cyclo

We report a striking example of unprecedented regiospecificity in the addition of acetic acid to endo-tricyclo[3.2.1.0z"]oct-6-ene (1). The addition proceeds with surprising ease in acetic acid at 80' (3 days) or at room temperature in the presence of catalytic amounts of toluenesulphonic acid to yi
