INSECTICIDAL COMPOSITION

PROBLEM TO BE SOLVED: To provide a composition that can exhibit effective insecticidal action on insect pests. SOLUTION: An insecticidal composition comprises, e.g., a compound represented by general formula (1) in the figure. [R1 is a C1-10 alkyl group or the like, where the alkyl group and the like may be substituted with a halogen atom or the like; R2 is a hydrogen atom or the like, or R2 may bind a methoxy group binding a carbon atom adjacent to a carbon atom which R2 binds, to form a -O-CH2-O- group.] SELECTED DRAWING: None COPYRIGHT: (C)2021,JPO&INPIT

Reactions of some terpenes and their derivatives with acylating agents in the presence of aluminosilicate catalysts

Reactions of camphene, α-fenchene, limonene, caryophyllene, α- and β-pinenes, verbenol, walterol, and verbenone with acylating agents in the presence of clay K-10 and wide-porous β-zeolite were studied. Presumable schemes and rules of the occurring proces

BF3-induced cyclobutane-opening of verbenone and its deconjugate homolog. Efficient preparation of o-mentha-1,8-dien-3-one and o-menth-1-en- 3-one in optically active forms

Starting with (+)-verbenone, readily obtainable from (+)-nopinone, enantioselective preparation of (S)-(+)-4-isopropenyl-, (S)-(-)-4-isopropyl- and (R)-(+)-4-(1-acetoxy-1-methylethyl)-3-methyl-2-cyclohexen-1-ones was accomplished with little loss of stereochemical integrity via BF3-induced cyclobutane-opening of (+)4-(methylene)nopinone. As we have developed an efficient chemical transformation of (+)-nopinone into (-)-verbenone, the present syntheses of the above cyclohexenones are formal syntheses of their enantiomers from (+)-nopinone.

Lewis Acids Catalysed Fries Rearrangement of Isopropylcresol Esters

In the course of the Fries rearrangement, aluminium chloride frequently induces migration or elimination of alkyl groups.The results obtained with titanium tetrachloride for the synthesis of vicinal o-hydroxyketones are compared with those obtained with aluminium chloride for some aliphatic and aromatic esters of isopropylcresols.In order to understand the migration and elimination processes occurring, the stabilities of the o-hydroxyketones are studied in the presence of aluminium chloride at different temperatures.Furthermore, all-vicinal o-hydroxyketones were prepared by the Fries rearrangement of 6-tert-butyl-p-thymol with titanium tetrachloride.
