摘要： A novel and efficient method is proposed for the synthetic preparation of a long-chain alkynyl compound in a one-pot reaction without isolating the intermediate from the reaction mixture. The inventive method comprises the steps of: (a) a Grignard coupling reaction of an .omega.-halogeno-1-alkynyl magnesium halide compound of the general formula X.sup.1 MgC.tbd.C(CH.sub.2).sub.n X.sup.2, in which X.sup.1 is a halogen atom, X.sup.2 is an atom of Br or I and n is 3 to 10, and a Grignard reagent of the general formula RMgX.sup.1, in which R is a group selected from the class consisting of alkyl groups, alkenyl groups, alkynyl groups, alkapolyenyl groups, aryl groups and hydrocarbon groups having protected hydroxy group to give an intermediate compound of the general formula X.sup.1 MgC.tbd.C(CH.sub.2).sub.n R; (b) subjecting the intermediate compound to a reaction with a reactant selected from the class consisting of C.sub.2 -synthons, C.sub.1 -synthons and chlorosilane compounds having reactivity with the intermediate compound at the X.sup.1 Mg-terminal; and (c) hydrolyzing the reaction product obtained in step (b).

摘要： The inventive method is particularly advantageous for the preparation of an unsaturated alcohol or aldehyde by the reduction of a corresponding unsaturated carboxylic acid since the unsaturated double bond in the starting acid is not hydrogenated by the reaction of reduction. The method comprises first reacting the starting acid with an alkyl chloroformate to form an intermediate compound by the dehydrochlorination and the intermediate compound is then reduced by using sodium borohydride as the reducing agent. The proportion of the aldehyde to alcohol in the product mixture can be controlled by modifying the amount of the reducing agent and/or the reaction time.

摘要： An improvement is proposed for the removal of the precipitates of a phosphine oxide compound as a by-product from a mixture thereof with an olefin compound obtained by the Wittig reaction for the preparation of the olefin compound from a phosphorane compound and a carbonyl compound. Instead of the conventional procedure of filtration to remove the precipitates, the mixture in a hydrocarbon solvent, after replacement of a non-hydrocarbon solvent with a hydrocarbon solvent, if necessary, is admixed with a lower carboxylic acid such as acetic acid so that the precipitates of the phosphine oxide are dissolved forming a viscous fluid which is immiscible with the mixture of the olefin compound and the hydrocarbon solvent. The fluid containing the dissolved phosphine oxide compound can be easily removed by phase separation so that a great increase is obtained in the yield of the desired olefin compound.

摘要： A cache package (for example, a flash memory package configured by flash memories) can execute a cache control process instead of a processor in a storage system by a request of the cache control process from the storage system. Consequently, time for the process that the processor of the storage system executes can be reduced and increase in a throughput can be achieved. For example, particularly the present invention is effective in real time data processing in OLTP (OnLine Transaction Processing) (for example, database processes in finance, medical service, Internet service, and government and public service). In addition, under the concept of recent EPR (Enterprise Resource Planning) a flexible storage system that can respond rapid fluctuation in an amount of data and an access load can be established and leveraged by increasing several boards of required cache packages.
