摘要: PROBLEM TO BE SOLVED: To produce a polyhydric alcohol from an olefin having a carbonyl group in high conversion and high selectivity. SOLUTION: When reacting the olefin having the carbonyl group and/or its protective group and an ethylenic double bond with oxygen and an alcohol in the presence of a catalyst to produce an acetal and/or ketal compound, the oxygen is previously brought into contact with the catalyst before starting reaction of the olefin. The acetal and/or the ketal compound produced by the method is hydrolyzed and reduced to produce the polyhydric alcohol. COPYRIGHT: (C)2004,JPO

摘要: PROBLEM TO BE SOLVED: To obtain the subject monoacetal compound in a high yield by specifying an initial distillation temperature on isolating glutaraldehyde monoacetal by a distillation from a crude reaction liquid obtained after reacting dihydropyranes with a diol. SOLUTION: This glutaraldehyde monoacetal of formula II is obtained by reacting 2-Y-3, 4-dihydro-2H-pyrane of formula I (Y is hydroxy, an alkoxy or the like) or its nuclear-substituted derivative with a diol of the formula: HOROH [R is a 1-10C (un) saturated hydrocarbon], (suitably ethylene glycol or 1, 2-propylene glycol). In isolating the compound of the formula II after the reaction, an initial distillation operation for removing a low boiling component from the crude reaction liquid, is conducted while maintaining the temperature of the distillation bottom liquid at 100-200 deg.C, preferably at 130-180 deg.C. The reaction of the compound of the formula I with the diol, is preferably performed by using a sulfonic acid type cation exchange resin as a catalyst at 30-150 deg.C. The distillation of the crude reaction liquid is preferably performed after the removal of the catalyst.

摘要: PROBLEM TO BE SOLVED: To obtain the subject new compound useful as an intermediate for agrochemicals, etc., in high yield by irradiating a specific compound and an oxygen-contg. compound with light in the presence of an aryl ketone compound. SOLUTION: This new compound is shown by formula I [R and R are each a (substituted) 1-6C alkyl or (substituted) aryl; R and R are each H or a 1-6C alkyl; X is H, a 1-6C alkyl or OR (R is H or a 1-6C alkyl); Ar is a (substituted) aryl], e.g. 4-ethylenedioxymethyl-3-(p-tolylsulfinyl)-2-pentanone. This compound of formula I is obtained by irradiating an α-sulfinyl enone compound of formula II [e.g. 3-p-tolysulfinyl)-3-penten-2-one] and an oxygen- contg. compound of formula III (e.g. methanol) with light using e.g. a mercury vapor lamp in the presence of an aryl ketone compound (e.g. benzophenone).
