A new, convenient and excellent yield procedure for the preparation of bis(indolyl)methanes(BIMs) by Friedel–Crafts reaction of indoles with imines in the presence of dithiocarbohydrazone Schiff base/ Zn(ClO4)2 6H2 O as a highly stable, effective and readily available catalyst is described. Moderate to good yields(up to 99% yield) were obtained with both substrates for imine derivatives. This procedure is simple, practical and economic.

山西既是能源化工大省,又是严重缺水省份,这是一个怪异的现象。山西缺水的程度很严重,浪费水的程度更严重,这是第二个怪异的现象。山西自身严重缺水,还要把水分给其他省、市,这是第三个怪异的现象。    5月9号,大雨。山西五台县水泉湾水源地工程现场空无一人,只有“建坪上应急引水工程,造福忻州人民”的标语牌在风雨中颤栗。这项规划总投资9.35亿元的滹沱河引水工程建成后,近期将为忻定盆地的定襄、原平、忻府区
