Abstract: The present invention relates to the field of perfumery. More particularly, it concerns compounds comprising at least one ?-thio carbonyl or nitrile moiety capable of liberating an active molecule selected from an ?,?-unsaturated ketone, aldehyde or nitrile. The present invention concerns also the use of said compounds in perfumery as well as the perfuming compositions or perfumed articles comprising the invention's compounds. (I) wherein: a) m represents an integer from 1 to 6; b) Pro represents a hydrogen atom or a group susceptible of generating an odoriferous ?,?-unsaturated ketone, aldehyde or nitrile and is represented by the formulae (II) or (II?) in which the wavy line indicates the location of the bond between said Pro and the sulfur atom S; and at least one of the Pro groups is of the formula (II) or (II?).

Abstract: The present invention relates to the manufacture of nitrile compounds from unsaturated organic compounds by reaction with hydrogen cyanide. It relates more particularly to the manufacture of nitrile compounds of use in the synthesis of adiponitrile, an important chemical intermediate in the manufacture of major chemical compounds, such as hexamethylenediamine and ?-caprolactam. The invention provides a process for the manufacture of organic compounds comprising at least one nitrile functional group by carrying out a hydrocyanation reaction between hydrogen cyanide and an organic compound comprising at least one ethylenic unsaturation. This reaction is carried out in the presence of a catalytic system comprising a metal element chosen from the group consisting of nickel, platinum and palladium and an organophosphorus ligand, the reaction medium additionally comprising an ionic liquid in the liquid state at least at the temperature at which the hydrocyanation reaction is carried out.

Abstract: This invention relates to a novel class of compounds which are cysteine protease inhibitors, including but not limited to, inhibitors of cathepsins K, L, S and B. These compounds are useful for treating diseases in which inhibition of bone resorption is indicated, such as osteoporosis.

Abstract: Amide and methide salts, comprising in the case of an amide salt one cyano (—CN) group, and in the case of a methide salt, two cyano groups are described in applications requiring a high degree of ionic dissociation. The salts are especially useful as electrolyte components in electrochemical cells such as batteries, fuel cells, capacitors, supercapacitors, electrochemical sensors and electrolytic cells, by providing a means for ionic conduction and transport.

Abstract: The invention discloses novel salicylate esters of silicone compounds which contain an ester linkage, and a silicone polymer. Compounds of the invention are made by reacting (a) a carboxy silicone, and (b) salicylic acid to form an ester. Compounds of the invention by virtue of (i) the silicone group, (ii) the ester group and (iii) the ultra violet absorbing group salicylic, the compounds are effective durable ultra violet absorbers.

Abstract: The present invention provides an ozonide reducing agent for use in the ozonolysis reaction of an organic compound, the ozonide reducing agent finding wide applications, and being safe and inexpensive from a commercial viewpoint and easy to treat for disposal.The ozonide reducing agent of the invention is a compound wherein sulfur has, at both ends of its molecule, a hydrocarbon residue substituted by a polar functional group.

Abstract: Oligomers with polydiene sequences and crosslinkable grafts are useful as coatings for protecting metal surfaces as well as inking buffers. The oligomers contain a polydiene sequence of 1-100 diene links, from 1 to 20 polar functional groups, and from 1-20 acrylic or methacrylic groups.

Abstract: A novel class of compounds has been found to be effective in blocking cholesterol and neutral lipid synthesis in-vivo without adversely affecting energy metabolism, useful for the treatment of obesity, hyperlipidemia and maturity-onset diabetes. The active compounds have the general formula ##STR1## or in-vivo hydrolyzable functional derivatives of the carboxylic groups thereof,whereinR.sub.1 and R.sub.2 each independently represents an unsubstituted or substituted hydrocarbyl or hetercyclyl radical;X and Y each independently represents hydrogen, optionally substituted lower alkyl, halogen, cyano, carboxy, lower alkoxycarbonyl or carbamoyl; andQ represents a diradical consisting of a linear chain of 8 to 14 carbon atoms, one or more of which may be replaced by heteroatoms, said chain being optionally substituted by inert substituents and one or more of said carbon or heteratom chain members optionally forming part of a ring structure.

Abstract: Compounds of the formula I ##STR1## where R is alkyl of 1 to 10, preferably 1 to 4, carbon atoms, X is O or S, Y is hydrogen or nitrophenyl which is unsubstituted or substituted by chlorine, bromine, methoxy or methyl, when n is 1, and is C.sub.2 -C.sub.6 -alkylene when n is 2, and Z is cyano or 2-benzimidazolyl, are prepared by a process in which an iminoether of the formula II ##STR2## is reacted with a compound of the formula III ##STR3## where A.sup..crclbar. is an anion. The compounds prepared according to the invention are useful intermediates, for example for the preparation of diazo components.

Abstract: The new halogenated sulphides of the formula ##STR1## in which R.sup.1 to R.sup.8 are identical or different and denote hydrogen or halogen, at least one of the radicals R.sup.1 to R.sup.8 representing halogen,and whereinR.sup.1 and R.sup.2, and/or R.sup.3 and R.sup.4 can optionally form an olefinic bond, andA and B are identical or different and denote nitrile, carboxyl, carboxylate or carboxamide,can be prepared by halogenation of bis-(cyanoethyl) sulphide, or by splitting off hydrogen halide from a halogenated bis-(cyanoethyl) sulphide, or by reacting 3-halogeno-acrylonitriles with sulphides. The new compounds can be active compounds in microbicidal agents.
