Abstract: A process for the production of a monochloromethyl ketone of the formula ##STR1## in which R.sup.1, R.sup.2 and R.sup.3 each independently is a hydrogen atom or an optionally substituted alkyl, alkenyl, alkinyl or aryl radical, orR.sup.1 and R.sup.2 together with the carbon atom to which they are attached form an optionally substituted carbocyclic ring,comprising reacting a 1,1-dichloroalkene of the formula ##STR2## with a phenolate of the formula ##STR3## in which R.sup.4 each independently is a halogen atom, a nitro group, or an optionally substituted alkyl, alkoxy or aryl radical,n is 0, 1, 2 or 3, andM is one equivalent of an alkali metal ion or alkaline earth metal ion,thereby to obtain a phenyl ether intermediate, and then subjecting the phenyl ether intermediate to an acid hydrolysis. The products are useful as intermediates in the synthesis of fungicides.

Abstract: 2,2'-bipyridinium chlorochromate has been found to be an effective oxidizing agent, particularly for the conversion of primary or secondary alcohols to their respective aldehydes or ketones.

Abstract: This invention is a method to restore the metal content of a supported noble metal hydrogenation catalyst comprising adding the appropriate amount of a noble metal salt of a weak acid to a fluid feed passing across the catalyst.

Abstract: The reduction of organic compounds is made more selective by modifying the reduction catalysts with compounds of sulfur.

Abstract: Alicyclic ketone and alcohol derivatives having the structure: ##STR1## wherein the dotted line represents a carbon-carbon double bond or a carbon-carbon single bond; wherein Z is ##STR2## and wherein each of R.sub.1, R.sub.2, R.sub.3, R.sub.4, and R.sub.5 is hydrogen or lower alkyl are useful as odor-modifying ingredients in perfumes and perfumed products and as flavor-modifying ingredients in foodstuffs and tobacco products.

Abstract: At least one of a polycyclic phenol, a polycyclic alcohol and a polycyclic ketone is produced under hydrogenation conditions using a nickel oxide/manganese oxide/magnesium oxide catalyst by subjecting at least one of a monocyclic ketone, a monocyclic alcohol and a monocyclic phenol to said conditions and said catalyst.

Abstract: New spirane derivatives useful as odor- and flavor-modifying ingredients for preparing perfumes, perfumed products, for the manufacture of artificial flavors or for flavoring foodstuffs, animal feeds, beverages, pharmaceutical preparations and tobacco products.

Abstract: A method for promoting the hydrogenation of phenol to cyclohexanone in the presence of a non-promoted palladium catalyst which comprises effecting the hydrogenation reaction in the presence of an in situ promoter selected from the group consisting of alkalie metal and alkaline earth metal chlorides, fluorides, bicarbonates, carbonates, hydroxides and nitrates, ammonia, ammonium hydroxide, secondary amines and mixtures thereof.

Abstract: This invention concerns processes for preparing compounds having the structure ##STR1## wherein each of R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6 is the same or different and represents hydrogen or a lower alkyl group and wherein each dashed line represents a carbon-carbon single bond or a carbon-carbon double bond. Those compounds in which all three dashed lines represent carbon-carbon double bonds are prepared by reacting phenols and 2-alkylidene-1,4-disubstituted butanes. Selective reduction of these compounds yields those in which at least one dashed line represents a carbon-carbon single bond. Most of the compounds so prepared are new compounds. All are useful as fragrance materials either directly and/or in compositions and/or have useful fixative properties in fragrance compositions.
