A ruthenium imidazole alkylidene reagent catalyzes a ring-closing reaction involving olefins and this type of ether, as reported by Rainier.
Aza versions of this moiety are produced from aldimines via deprotonation, and thos aza versions are the conjugate bases of hydrazones. A ruthenium imidazole alkylidene reagent catalyzes a ring-closing reaction involving olefins and this type of ether, as reported by Rainier. They can be synthesized by the addition of a Gilman reagent to an alpha,beta-unsaturated ketone. The attack of a Grignard reagent upon the beta carbon of an unsaturated ketone producs this moiety as a (*) 1,4-adduct. One of these reacts with a carbonyl to form a beta-hydroxyketone in the aldol reaction. Under standard conditions, this group is present in much lower concentrations than its tautomer, a carbonyl group. For 10 points, name this functional group that consists of a carbon-carbon double bond with a hydroxyl group on one of the carbons.
