The 1, 3, 4-Oxadiazole and 1, 3, 4-Thiadiazole coupling of Norbornenes and 7-Oxanorbornenes Under High Pressure - New Structures, Mechanistic Detail and Synthetic Applications
A comparison of reactivities, site selectivities, calculation and thermal versus high pressure (14 kbar) reaction conditions are used in a study of the coupling of bicyclic alkenes with 1, 3, 4-oxadiazoles (and 1, 3, 4-thiadiazoles) which sets the boundary conditions for such coupling and identifies a 1, 3-dipolar species as the likely intermediate.
