Khera, Rasheed Ahmad published the artcileSynthesis of fluorinated 2,3-dihydropyran-4-ones by cyclocondensation of 1,3-dicarbonyl dianions with aldehydes, Category: chlorides-buliding-blocks, the main research area is pyranone dihydrotrifluoromethyl preparation; pentanedione fluorinated aldehyde cyclocondensation.
The reaction of the dianion of 1,1,1-trifluoro-pentane-2,4-dione with aldehydes and subsequent addition of hydrochloric acid afforded 2,3-dihydro-6-trifluoromethyl-pyran-4-ones. The reaction of the dianion of acetylacetone with fluorinated benzaldehydes gave the corresponding fluorinated 2-aryl-2,3-dihydro-6-methyl-pyran-4-ones. All reactions proceeded in very good yield and with very good regioselectivity. While 2 crystal structures were determined, no data are reported here.
Journal of Fluorine Chemistry published new progress about Aldehydes Role: RCT (Reactant), RACT (Reactant or Reagent). 93118-03-7 belongs to class chlorides-buliding-blocks, name is 2-Chloro-3-(trifluoromethyl)benzaldehyde, and the molecular formula is C8H4ClF3O, Category: chlorides-buliding-blocks.
