    摘要: An improved process for the manufacture of cis-8-dodecen-1-ol acetate, the sex pheromone of the oriental fruit moth Cydia molesta, comprises the steps of: i. reacting 1-chloro-6-iodohexane with pent-1-yne in liquid ammonia in the presence of lithium amide as a catalyst; ii. reacting the product of step (i) with an alkali metal cyanide in the presence of a metal iodide as catalyst; iii. subjecting the product of step (ii) to alkaline hydrolysis; iv. reducing the product of step (iii) with sodium bis(methoxyethoxy) aluminium hydride; v. acetylating the product of step (iv); and vi. reducing the product of step (v) with bis(sec-isoamyl)borane.

    摘要: New Insecticides comprising 1,1-bis(4-substituted phenyl)-2nitropropanes,-2-nitrobutanes and -2- methyl-2-nitropropanes wherein the 4-substituents of the phenyl radicals are nonidentical lower alkoxy groups, or identical or non-identical alkylthio groups, and such compounds wherein one of the 4substituents is replaced by a 3,4-methylene-dioxy group. These compounds are prepared by condensing the appropriate psubstituted-benzaldehyde with the appropriate nitro-alkane and reacting the carbinol product with the appropriately substituted benzene.
