摘 要：Metallophthalocyanines have many interesting properties and applications in several important technological fields,such as conductivity,chemical catalysis,photoelectric effect and nonlinear optical *** are very well known to catalyze a variety of organic reactions,so investigation into the redox properties of MPcs continue to be active areas of ***,due to their strong tendency towards aggregation and difficulty in separation from reaction mixture,immobilization of MPcs on activated carbon supports is carried out to make catalysts recoverable and *** group is interested in one-pot synthesis of heterocyclws via metallophthalocyanines-catalyzed addition/cyclization reactions,which provide economic,convenient and efficient approaches to potentially useful heterocyclic *** we report a highly selective one pot synthesis of functionalized N-alkyl substituted hydrazones by a simple condensation reaction of decomposing two equivalents of tosylhydrazones in the presence of a catalytic amount of CuPc@C was carried out and resulted in high product *** procedure proves to be advantageous in terms of low cost,high efficiency,high yield,simple operation,and wide application range,with a recyclable and therefore environmentally beneficial catalyst species.
