Methylcyclopropane
Methylcyclopropane is the alkyl cycloalkane compound of methane and cyclopropane.
Usage
It is used as functional group in tertiary amines .
Reactions
The small alkylcycloalkanes - particulary alkylcycloprapane - has a lower stability due to the Baeyer-tension . They react similar to alkenes, though they dont react with the EA (cf. electrophilic addition), but with the SN2 (cf. nucleophilic substitution) reaction mechanism. These reactions are both ring opening reactions and cleavage reactions. The typical reaction is the hydro halogination .
- H3C-CycProp + HBr → H3C-CHCl-CH2-CH3 (ring opening reaction )
- H3C-CycProp + HBr → H3C-H + Cl-CycProp (cleavage reaction )
The latter reaction is important due to cleavage of the cyclopropyl-ring in tertiary amines .
