A matrix isolation study of the photochemically induced reactions of nitrogen dioxide with 1,2-dibromoethene and 1,2-dichloroethene using Fourier transform infrared spectroscopy

Photolyses of matrices of either BrCHCHBr/NO2/Ar or ClCHCHCl/NO2/Ar using quartz-filtered radiation (λ > 240 nm) led to the appearance of infrared bands attributable to carbonyl, carbon monoxide, and ketene species; no bands belonging to a precursor complex NO 2...XCHCHX (where X = Br or Cl) were observed upon matrix deposition. The possible reaction pathway is discussed.

The Phosphorylation of Organic Compounds by Phosphoric Anhydride. Part 3. Synthesis of Monosubstituted Ketenes in the Reaction of Esters with Phosphoric Anhydride and cyclotrimerization of these Ketenes

Monosubstituted ketenes 1 have been synthesized from substituted acetic esters 2 by elimination of alcohol under the action of phosphoric anhydride.The ketenes undergo cyclotrimerization to give substituted phloroglucinols (1,3,5-trihydroxybenzenes) 3 and their phosphorylated derivatives.
