Oxidative α coupling of carbonyl compounds via the condensation of acylated triazolinedione ylides with enolates: A facile synthesis of polyacylated olefins

α-Urazolyl ketones are readily oxidized to acylated N-phenyltriazolinedione ylides with tert-butyl hypochlorite. These ylides, usually as generated in situ, undergo condensations with enolate species to form acylated olefins in synthetically useful yields

The Reaction of Cyclic 1,3-Diketones with Alkylcyclopropenium Ions to Yield 2-Alkyltihio-substituted 2H-Pyrans

This study treats the reactions of methylthio-, ethylthio-, or benzylthiodiphenylcyclopropenium ion(1) with 5-, 6-, and 7-membered cyclic 1,3-diketones, giving either 2-alkylthio-2H-pyrans or dienone derivatives.Treatment of 1 with 1,3-cyclopentanedione,
