also gave a little norbornanone (presumably from the dioxetane) and 5 gave some endo-3,7,7-trimethylnorbornan-2-one as a secondary photo-product. It was found that the exo/endo attack ratios by singletoxygen on 3 and 5 are 66 and 0.19. By exploiting the C (3) monodeuteriated derivatives, 4 and 6 showed ratios of 28 and 0.67.

Gas phase pyrolysis of 1-sila-2-oxynorbornenes yields a nortricyclene which is proposed to arise from a β-elimination to form a 1-norbornene, which isomerizes to a 2-norbornacylidene which undergoes γ-CH insertion.
