Regioselectivity in the Ring Opening of 2-Alkylcyclopropylmethyl Radicals: the Effect of Electronegative Substituents

The regioselectivity of the ring-opening of the trans-2-alkylcyclopropylmethyl radical A to give the primary alkyl radicals B, or the secondary alkyl radicals C, has been investigated, where the groups R and/or CXY carry electronegative substituents.All these reactions gave principally the secondary alkyl radicals C, whereas, in the absence of electronegative substituents, ring-opening occurs in favour of the primary alkyl radicals B.This regioselectivity is interpreted in terms of the frontier orbital interactions which are involved.

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.
