C-acylation of 1,3-diketo compounds has been done successfully employing 1,3 diketo compounds, oxalyl chloride, and phenol derivatives through metal, base, and toxic solvent-free protocol. Dioxinone ring-bearing 1,3,3' tricarbonyl moiety was also obtained in the same conditions using salicyl aldehyde. All reactions were carried out in vegetable oil.
