- An Unusually Strict Product Partition of an Excited Diazirine-Carbene System
-
Photolysis of 3-tert-butyl-3-chlorodiazirine produces 2-chloro-3-methyl-but-2-ene and 2,2-dimethyl-1-chlorocyclopropane; the former stems from 1,2-methyl migration and nitrogen loss in the excited state diazirine, whilst the latter is a product of 1,3-CH insertion in the tert-butylchlorocarbene derived from the diazirine.

- Reactions of Hydrogen Chloride with 3-Methyl-1-butyne: Cycloaddition and Rearrangement Reactions via Vinyl Cations
-
3-Methyl-1-butyne was reacted with anhydrous hydrogen chloride in the liquid phase at ambient temperatures.A total of 12 products were identified: three monoadducts (4, 6, 9), three diadducts (5, 7, 10), one substitution product (8), as well as five cycloaddition products having cyclobutane structures (11-15).Model reactions provided evidence for the mode of formation of the reaction products.
