title: Imidazolium ylides from a conjugate addition-proton transfer route and their cycloaddition reactions.
abstract: 4,5-Dihydroimidazolium ylides formed by conjugate addition-proton transfer from dihydroimidazoles and doubly-activated electron-deficient alkenes afford 2:1 cycloadducts in a one-pot process wherein the alkene also acts as a dipolarophile.
