摘要:Provided is a novel process for the synthesis of aryl sulfides substituted with an alkoxy or phenoxy substituent. The process comprises reacting an alkoxy or phenoxy substituted aromatic compound with a sulfur dihalide, preferably sulfur dichloride, in the presence of an alkali metal tetrafluoroborate catalyst, with the amount of said aromatic reactant compound preferably being sufficient to solvate the sulfur dichloride and catalyst sufficiently to allow the reaction to occur.

标题:Method for the synthesis of quaternary ammonium salts
发明人：NAKANO SHINJI; MORIMOTO TAKAO; ENDO TAKESHI
权利人:NIPPON PAINT CO LTD
摘要:Provided is a convenient method for the synthesis of quaternary ammonium sulfonate compounds which are useful as curing catalysts for one-part thermosetting resin compositions which maintain storage stability at room temperature. The compounds are synthesized by subjecting in one step a benzyl alcohol optionally having on the benzene ring and/or the α-position one or more substituent groups to reaction with a corresponding tertiary amine and an organic sulfonic acid chloride.

摘要:α,β-Unsaturated aldehydes are useful products as such in agrochemistry, but also potential intermediates for the preparation of important insect pheromones and kairomones. Until now, primarily the thermodynamically more stable (E)-α,β-unsaturated aldehydes have been identified as useful intermediates in the production of conjugated diene pheromone compounds, however, their practical and cost-effective synthesis on an industrial scale remains challenging. The problem to be solved by the present invention is to provide a method for selective oxidation of alkenes to α,β-unsaturated carbonyls which can be further transformed into pheromones and kairomones preferably without isolation and significant loss of the existing stereochemical purity.
