Abstract: A process for preparing bisphenol sulfone derivatives represented by the general formula (I) ##STR1## where R stands for hydrogen, a halogen, an alkyl radical, a cycloalkyl radical, an aryl radical, an aralkyl radical, hydroxyl group, an alkoxy radical, allyloxy group, carboxyl group, or a carboalkoxy radical, m is an integer of from 1 to 3, and when m is 2 or more, R may be identical to or different from each other, and adjacent Rs may be combined to form a ring, by oxidizing with hydrogen peroxide a compound represented by the general formula (II) ##STR2## where R and m have the same meanings as defined for the formula (I), and n is zero or 1, in the presence of an alkali in an amount more than the equimolar amount thereof relative to said compound in water and/or an organic solvent which do not form any organic peracids under reaction conditions.

Abstract: Benzenoid ethers/thioethers are prepared by reacting an activated halobenzene with an anionic reactant, RA.sup.- M.sup.+, in the presence of at least one tertiary amine sequestering agent having formula:N--CHR.sub.1 --CHR.sub.2 --O--CHR.sub.3 --CHR.sub.4 --O--.sub.n R.sub.5 ].sub.

Abstract: Disclosed herein are a novel compound, 3-n-propylsulfonylphenyl 4'-trifluoromethylphenyl ether and a herbicide composition containing the same as an active ingredient.

Abstract: The novel hydroquinone derivatives of the formula (I) are useful intermediates for the preparation of coenzyme Q, vitamin K and the polyprenyltrimethylquinones: ##STR1## wherein R.sup.1 is lower alkyl, lower alkoxy lower alkyl or methoxyethoxymethyl, R.sup.2 and R.sup.3 are each methyl or methoxy, or R.sup.2 and R.sup.3, taken together with the carbon atoms from which they depend, define a benzene ring, and R.sup.4 is a substituted or unsubstituted aromatic hydrocarbon. The compounds (I) are readily prepared either by reacting a Grignard reagent of the formula (II) with a halosulfone (III) in the presence of a copper compound, or by reacting a copper derivative (II') of the Grignard reagent (II) with a halo-sulfone (III), as follows: ##STR2## wherein R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are defined as above, and X is a halogen atom or a tosyl group.

Abstract: Hydroxyalkylphenyl ether compounds are prepared by reaction of cyclic organic carbonate compounds with phenols in the presence of potassium iodide catalyst.

Abstract: This invention provides a convenient and commercially adaptable process for the preparation of vinylcyclopropane derivatives in high yields. The process involves reacting an alkylating agent and an activated methylene compound in the presence of an onium compound, an alkali metal compound and water, which while only necessary in trace amounts can be present in substantial quantities.

Abstract: Phenolic materials containing propargyl groups are prepared by reacting a polyhydric, phenolic material with propargyl bromide, the reaction being conducted in an aqueous sodium hydroxide solution. The products can be thermally polymerized to polymers which are useful as adhesives and as matrix resins in the fabrication of composites.

Abstract: Linear dimers of certain bisphenols are provided by heating together a monocapped bisphenol salt and a certain dihalogenated alkylene or alkarylene compound in the presence of an inert organic solvent. The linear bisphenol dimers are useful as anti-oxidants and intermediates for making polycarbonates, polyesters and block polymers.

Abstract: An improved process for obtaining halogenated diphenols which can be pure dihalodiphenols or predetermined, statistical mixtures comprising unreacted diphenol, monohalodiphenols and dihalodiphenols.
