  The invention relates to a process for the preparation, in a single step, of substituted 2-cyclopenten-1-ones by reacting a substituted enone with an aldehyde in the presence of a catalytic system. The catalytic system consists of a metal complex, such as a Ti(Cl) 3 (alkoxy), and a co-ingredient, such as a carboxylic acid anhydride or an anhydrous salt.

  本发明涉及一种制备取代的2-环戊烯-1-酮的方法，该方法通过在催化剂体系的存在下，将取代的烯酮与醛在单个步骤中反应。催化剂体系由金属配合物（例如Ti(Cl)3(烷氧基)）和共同成分（例如羧酸酐或无水盐）组成。

  A compound of the formula (1) wherein R1 and R5 each represents an alkyl group having 1 to3 3 carbon atoms; R2, R3 and R4 each represents a hydrogen atom or an alkyl group having 1 to 3 carbon atoms and wherein the bonding at the 2-3 position is a single bond and that at the 3-4 position is a double when the substitution of hydroxy group is at the 5-position or the bonding at the 2-3 position is a double bond and that at the 3-4 position is a single bond when the substitution of hydroxy group is at the 7-position:; with the proviso that R2 and R4 should not be a hydrogen atom or an alkyl group simultaneously. Such a compound can be prepared by reacting resorcinol with an aliphatic ketone or a tertiary alcohol or by thermally decomposing polyalkyl (2, 4 - dihydroxyphenyl) hydroxychroman. The compound is useful as a herbicide and fungicide and as an intermediate for preparing agricultural chemicals.

  Provided herein are methods for producing cyclic and acyclic ketones from trimerization and dimerization of alkyl ketones, including for example methyl ketones. Such cyclic and acyclic ketones may be suitable for use as fuel and lubricant precursors, and may be hydrodeoxygenated to form their corresponding cycloalkanes and alkanes. Such cycloalkanes and alkanes may be suitable for use as fuels, including jet fuels, and lubricants.
