Synthesis of 3-chloro-4-methyl-6-(trichlorovinyl)-2-pyrone from 1,1,2,3-tetrachloro-1,3-butadiene and some of its reactions. Akopyan, A. N.; Saakyan, A. M.; Safaryan, A. A. (Inst. Org. Khim., Yerevan, USSR). Arm. Khim. Zh., 29(4), 323-5 (Russian) 1976. CODEN: AYKZAN. DOCUMENT TYPE: Journal CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) Treatment of MeCOCCl:CCl2 (I) with H2SO4 gave 63.5% pyrone II, which was also obtained in 91.7% yield by treatment of Cl2C:CClCCl:CH2 with H2SO4. The toxic intermediate I was not formed in the latter method. Treatment of II with NH4OAc gave 88.8% pyridone III. IV was also prepd. from II by nitration. .
