Thermal and Photochemical Reactions of Acetylenes: I-Ortho-Effect in the Bergman Cyclization of Benzannelated Enediynes II-Photocycloaddition of Diaryl Acetylenes to Cyclic Dienes Mechanisms and Applications
Four different sources of kinetic information were combined to study the effect of ortho substituents on the rate of Bergman cycloaromatization. All of these methods confirm that the cyclization barrier is highly sensitive to the nature of ortho-substituents. However, the measured activation energie...
