Abstract: Abstract A novel synthesis of functionalized 1,2,4-triones via an oxidative homo-coupling of β-keto sulfoxonium ylides is presented. Preliminary mechanistic study reveals that the formation of the 1,2,4-trione product involves the in situ generation of an… read more here.

Abstract: Previous transition metal-catalyzed synthesis processes of δ-diketones are plagued by the high cost of the rhodium catalyst and harsh reaction conditions. Herein a low-cost, room temperature ruthenium catalytic method is developed based on the coupling… read more here.
