  2-(2-Haloalkenyl)-aryl halides, conveniently prepared in a single step from the corresponding o-halobenzaldehydes, are combined with amines under Pd catalysis to provide 1-substituted indoles. All combinations of Br and Cl leaving groups can be employed, and a range of substituents on the arene, alkene and amine, can all be tolerated. The use of 1,3-dichloro-substituted arenes allows a third amination

  由一步法从相应的邻卤代苯甲醛方便地制备的2-（2-卤代烯基）-芳基卤化物在Pd催化下与胺结合，得到1-取代的吲哚。可以使用Br和Cl离去基团的所有组合，并且芳烃，烯烃和胺上的一系列取代基都可以被接受。使用1，3-二氯取代的芳烃可以进行第三次胺化过程。这些三组分方法以良好的产率提供了相应的4-氨基吲哚。

  Chloromethyltriphenylphosphonium iodide has been prepared by the reaction of chloroiodomethane with triphenylphosphine. Upon treatment with potassium t-butoxide in t-butyl alcohol, the phosphonium iodide was converted into chloromethylenetriphenylphosphorane; this in turn was used for the Wittig reaction of aldehydes and ketones into the corresponding chloroolefins of the type RCH=CHCl and RR′C=CHCl in

  氯甲基三苯基碘化鏻已通过氯碘甲烷与三苯基膦反应制备。用叔丁醇中的叔丁醇钾处理后，碘化鏻转化为氯亚甲基三苯基正膦；这反过来又用于醛和酮的 Wittig 反应，生成相应的 RCH=CHCl 和 RR'C=CHCl 类型的氯烯烃，收率良好至中等。这些氯烯烃的构型是根据 NMR 光谱研究确定的。使用鏻盐和过量的叔丁醇钾也可以将苯甲醛直接转化为苯乙炔。

  It is an object of the present invention to provide a polymer composition including a polymer produced by cationic polymerization in which the composition does not liberate a chlorine component by heating, which prevent processing apparatus, driers, etc. from corroding, and which is odorless and safe. The object is achieved by a polymer composition obtained by adding a double salt containing magnesium and aluminum as metal atoms to a polymer containing chlorine atoms produced by polymerizing cationically polymerizable monomers with an initiator in the presence of a Lewis acid.
