Abstract
2-Vinyl- and 2-ethylcyclopropanes having an aryl group and a nitrogen-containing radical substituted at the 1-position on the ring are provided. The novel 1,1-disubstituted 2-vinylcyclopropane and 2-ethylcyclopropane compounds of this invention have utility in herbicidal applications and are useful reactants. The 2-vinylcyclopropane derivatives are useful monomers for anionic and radical polymerizations.
