SUBSTITUTED 4-METHYLENE-TETRAHYDROPYRANS, 4-METHYL-DIHYDROPYRANS AND 4-METHYL-TETRAHYDROPYRANS AND USE THEREOF AS AROMA CHEMICALS

The present invention relates to substituted 4-methylene-tetrahydropyrans, 4-methyl- dihydropyrans and 4-methyl-tetrahydropyrans of formula (I), where the variables are as defined in the claims and description, to a stereoisomer thereof, to a mixture of stereoisomers thereof, to a mixture of different di- and tetrahydropyrans (I) and to a mixture containing at least one di- or tetrahydropyran (I) and at least one cyclic acetal which is a 1,3-dioxan carrying in 2-position an isobutanol-2-yl- (derived) substituent and in 4,4- or 5,5-position two methyl substituents. The invention also relates to the use of such compounds as an aroma chemical and/or for modifying and/or enhancing the aroma of a composition, to compositions comprising such compounds, to methods for preparing such compounds and to a product obtainable by these methods.

DIACRYLATE-COMPOUND-CONTAINING COMPOSITION AND CURED PRODUCT THEREOF

The present invention relates to a limited composition containing a diacrylate compound represented by general formula (1). In the formula, R denotes a hydrogen atom or a methyl group. The present invention provides a diacrylate-compound-containing composition which provides a cured product having excellent physical properties such as low curing shrinkage, flexibility, resistance to bending, and low curling properties, and which can be used as a photo- or thermal-radical polymerizable composition and a cured product of the composition.

ESTER COMPOUND, AND LUBRICATING-OIL AND LUBRICATING-OIL BASE OIL

PROBLEM TO BE SOLVED: To provide a novel di-neopentyl type ester compound that can easily be synthesized under a mild reaction condition from a variety of carboxylic acids and carboxylic acid esters and is excellent in viscosity index, heat resistance and color number. SOLUTION: Provided are an ester compound represented by the following formula (1), and a lubricating-oil containing the compound. In the formula, R1 and R2 are, each independently, selected from a straight chain saturated alkyl group, branched saturated alkyl group, straight chain unsaturated alkyl group and branched unsaturated alkyl group having 1 to 20 carbon atoms, and R3 and R4 are, each independently, selected from a straight-chain alkyl group and branched alkyl group having 1 to 6 carbon atoms.

Maleimido-bearing compounds resin composition containing the same and cured articles thereof

The present invention provides (meth)acrylate compounds bearing a specific maleimide group and resin compositions containing said compounds that can be cured by irradiation of light in a practical dose even when a photoinitiator is not used or used in a smaller amount than that of the prior art, and cured articles of the resin compositions.

Synthesis of 3,6-Dichloro-4-(2-chloro-1,1-dimethylethyl)pyridazine

3,6-Dichloro-4-(2-chloro-1,1-dimethylethyl)pyridazine (3) is a systemic plant fungicide whose synthesis by several routes is described.Free-radical alkylations of 3,6-dichloropyridazine (1) gave either the 4-tert-butyl derivative 2 or the alcohol 3,6-dichloro-β,β-dimethyl-4-pyridazineethanol (24).Pyridazine (2) must be subjected to a free-radical chlorination, which resulted in other products, but alcohol 24 could be smoothly converted to 3.Alternatively, the pyridazine ring was constructed with the side chain preattached by utilizing lactone intermediates 10 or 18.The lactone 10 with hydrazine yielded the ether 11, and chlorination with ether cleavage proceeded to 3.Lactone 20 could not be transformed to 3.
