  A phenylacetone or its derivative having the general formula (I): wherein X. Y, and Z are independently a hydrogen atom, a hydroxyl group, a halogen atom, a nitro group, an amino group, a lower alkyl group having 1 to 6 carbon atoms, a lower alkoxy group having 1 to 6 carbon atoms, or a benzyloxy group and any two substituents of X, Y, and Z may form, together with the benzene ring, a heterocycling ring having 5 to 7 members including 1 or 2 oxygen atoms is produced at a high yield and a high selectivity by reacting a 3-phenylpropylene or its derivative having the general formula (II): wherein X, Y and Z are as defined above, with an alkyl nitrite having the general formula (III):wherein R is an aliphatic, aromatic or alicyclic saturated or unsaturated hydrocarbon group in the presence of (a) water, (b) an alcohol, (c) a palladium catalyst, and (d) an optional amine or copper compound, or by reacting the above-mentioned 3-phenylpropylene or its derivative with the above-mentioned alkyl nitrite in the presence of (a) an alcohol, (b) a palladium catalyst and (c) an optional amine or copper compound to form 1-phemrl-2,2-dialkoxypropane or it derivative having the general formula (IV): wherein X, Y, Z and R are as defined above, followed by hydrolyzing the reaction product.

  具有通式(I)的苯丙酮或其衍生物： 其中 X.Y和Z独立地为氢原子、羟基、卤素原子、硝基、氨基、1至6个碳原子的低级烷基、1至6个碳原子的低级烷氧基或苄氧基，且X、Y和Z的任意两个取代基可与苯环一起形成一个具有5至7个成员（包括1或2个氧原子）的杂环： 其中 X、Y 和 Z 如上定义，与通式（III）的亚硝酸烷基酯反应：其中 R 为脂肪族、芳香族或脂环族饱和或不饱和烃基，在 (a) 水、(b) 醇、(c) 钯催化剂和 (d) 任选胺或铜化合物存在下反应、或在(a)醇、(b)钯催化剂和(c)任选胺或铜化合物存在下，使上述 3-苯基丙烯或其衍生物与上述亚硝酸烷基酯反应，生成通式为(IV)的 1-苯基-2,2-二烷氧基丙烷或其衍生物： 其中 X、Y、Z 和 R 如上定义，然后水解反应产物。
