“…[Si( O-CH=CH-COR )4] -> 4RCOCH=CHCl + Si(OAlCl2) 4 Prins and Haring (199) prepared trichloromethyl ßchlorovinyl ketone through condensation of methyl a, /3,/3,/3-tetrachloroethyl ether with cfs-l,2-dichloroethylene in the presence of aluminum chloride. Finally, Wichterle and Vogel (224) prepared methyl /3-chlorovinyl ketone by treating methyl /3,/3-dichlorovinyl ketone with zinc dust in ethanol, while Petrov and Sopov (191) treated l-chloro-3-methoxy-l,3-butadiene with 5% sulfuric acid to obtain the same product. In each of these cases the starting materials are not readily available.…”

“…RCOCH=CHCl (section II), although it is not nearly as extensive (see Table XXX). These ß,ß-dichlorovinyl ketones readily react at the carbonyl group to form 2,4-dinitrophenylhydrazones (66) and semicarbazones (224). The addition of Grignard reagents again results in the corresponding ß,ß-dichlorovinylcarbinols in good yields (47,66,224).…”

By reaction of triacetic lactone with phosphoryl chloride 4-chloro-6-methyl-2-pyrone was prepared; this happened to be identical with a compound of uncertain structure, previously obtained from acetyl chloride and 1.1 -dichloroethene. Reductive dechlorination yielded 6-methyl-2-pyrone.Both 6-cyclopentyl-3cyclopentylcarbonyl4hydroxy-2-pyrone and 6-cyclopen-tyl4hydroxy-2-pyrone were prepared by conventional methods ; they have bacteriostatic properties. By chlorination and reduction of the latter compound 6-cyclopentyl-2-pyrone was obtained.The mechanism of these substitution reactions is discussed.Les alcoyl-6 pyrones-2 ne sont gutre connues. La cyclopentyl-6 pyrone-2, compose apparent6 a la lumi-auxone 1, a t t t synthttiste par Boldingh 2, tandis que la methyl-6 pyrone-2 a Ctt obtenue en quantite ntgligeable 3.
