  Synthesis of Fatty Trichloromethyl-β-diketones and New 1H-Pyrazoles as Unusual FAMEs and FAEEs

  摘要：

  The efficient synthesis of new fatty 1,1,1-trichloro-4-methoxy-3-alken-2-ones [Cl3CC(O)C(R-2)=C(R-1)OMe, where R-1=n-hexyl, heptyl, nonyl, undecyl, tridecyl and R-2 = H] and 1,1,1-trichloro-2,4-alkanediones [Cl3CC(O)(CHRC)-C-2(O)R-1, where R-1 = n-pentyl and R-2 = Me, R-1 = Et and R-2 = n-butyl, R-1 = n-butyl and R-2 = n-propyl] in good yields (85-95%) from acetal acylation with trichloroacetyl chloride is reported. The fatty 1,1,1-trichloro-4-methoxy-3-alken-2-ones and 1,1,1-trichloro-2,4-alkanediones were reacted with hydrazine hydrochloride, leading to respective 1H-pyrazole-5-carboxylates, unusual class of fatty acid methyl (FAMEs) and ethyl (FAEEs) esters. Their structures were confirmed by elemental analysis and H-1 and C-13 nuclear magnetic resonance (NMR). The fatty 1,1,1-trichloro-4-methoxy-3-alken-2-ones and 1H-pyrazole derivatives are new oleochemicals with potentially interesting and differential properties.

  give previously unknown structures of 1-hydroperoxy-1'-alkoxyperoxides in yields up to 64%. The same compounds are formed in the iodine-catalyzed reactions of geminal bishydroperoxides with enol ethers. The nature of the solvent has a decisive influence on the formation of 1-hydroperoxy-1'-alkoxyperoxides. In the series of Et(2)O, THF, EtOH, CHCl(3), CH(3)CN, and hexane, the best results were obtained

  A series of functionalized 1,1,1-trihalo-4-methoxy-3-alken-2-ones [CX3C(O)CR1=CROMe, where X = F or Cl; R = n-heptyl, n-octyl, n-nonyl, n-decyl, n-undecyl, n-tridecyl, (CH2)(2)CH=C(Me)(2), (CH2)(2)Ph, (CH2)(2)-(4-HOC6H4), (CH2)(2)-(4-MeOC6H4), (CH2)(2)CO2Me, (CH2)(3)CO2Me, CH(SMe)CH3, CH2(2-MeOC6H4), and R-1 = H, and R = H and R-1 = n-decyl] were synthesized from respective alkyl methyl ketones or aldehyde via acetal acylation using trifluoroacetic anhydride and trichloroacetyl chloride. 1,1,1-Trihalo-4-methoxy-3-alken-2-ones with acid-compatible substituents were easily hydrolyzed to respective trihalomethyl-1,3-diketones. The 1,1,1-trihalo-4-methoxy-3-alken-2-ones and/or respective trihalomethyl-1,3-diketones were reacted regiospecifically with hydroxylamine hydrochloride, leading to isoxazole derivatives, and with hydrazines, leading to respective 1H-pyrazole derivatives. The structures of all compounds were assigned based on nuclear magnetic resonance (NMR) and mass spectrometric data. This method represents an efficient pathway for the regioselective trihaloacetylation of asymmetrically substituted alkyl methyl ketones and highly self-condensing aldehydes. Moreover, this approach allows the introduction of biologically recognizable moieties, such as those from levulinic acid, sulcatone (prenyl), benzylacetone, anisylacetone, and raspberry ketone, as synthetic molecular targets.

  A solid catalyst for olefin polymerization and a process for producing an olefin polymer are provided. The polymer has a small content of a component which is dissolved out into a low temperature organic solvent, such as a low-molecular weight component and an amorphous component. The solid catalyst is obtained by bringing a solid catalyst component for olefin polymerization containing a titanium atom, a magnesium atom, a halogen atom, and an aliphatic carboxylate; an organoaluminum compound; and a compound represented by formula (I) into contact with each other: wherein R 1 is a hydrocarbyl group having 1 to 10 carbon atoms, R 2 is a hydrogen atom, a halogen atom or a hydrocarbyl group having 1 to 16 carbon atoms, and the R 1 the R 2 groups are independently the same or different, and the respective R 1 groups and R 2 groups may be joined with each other to form a ring.
