  effective green approach of Knoevenagel condensation and arylidene formation with the substrates involves pyrazole-3-carbaldehydes and active methylenes under catalytic action of glycine (the simplest amino acid) in dimethylsulfoxide. These reactions were successfully carried out at room temperature. GRAPHICAL ABSTRACT

  Abstract Sulfamic acid (SA) is a bi-functional, cost-effective and reusable green catalyst for the synthesis of 4-(pyrazol-4-yl)methylenepyrazol-5(4 H )-one derivatives by one-pot, three-component condensation of pyrazol-4-carbaxaldehydes, β -ketoesters and phenyl hydrazine (Route-I). In addition to this method, another simple condensation of pyrazol-4-carbaxaldehydes with pyrazolone in the presence

  摘要氨基磺酸（SA）是一种双功能，经济高效且可重复使用的绿色催化剂，用于通过一锅，三组分合成4-（吡唑-4-基）亚甲基吡唑-5（4 H）-一衍生物。吡唑-4-氨基甲醛，β-酮酸酯和苯基肼的缩合反应（路线Ⅰ）。除此方法外，还报道了在无溶剂条件下，在SA的存在下，吡唑-4-氨基甲醛与吡唑酮的另一种简单缩合反应，收率很高。这些方案的优点是条件温和，无水后处理，收率高，催化剂容易获得，无需色谱分离和廉价的固体酸催化剂。此外，SA可以循环使用五次而不会失去其催化活性。

  A series of pyrazole based D-pi-A derivatives with large stokes shift have been synthesized from 1,3-dipheny-1H-pyrazole-3-carbaldehyde by reacting with a series of active methylenes and characterized by spectroscopic analysis. The synthesized dyes show blue to red solid state emissions in the range of 441 -604 nm. All the pyrazole dyes, except dye 2.3.6.4-((1,3-dipheny-1H-pyrazole-4-yl)methylene)-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one, display solid state emission characteristics. Experimental absorption and emission wavelengths measured for all the synthesized dyes are in good agreement with those predicted using the Time-Dependent Density Functional Theory. In this paper, the static first, second hyperpolarizability and its related properties estimated for pyrazole based "push-pull" dyes using B3LYP functional with 6-311G(d) basis sets. We have performed experimental calculation to determine the first hyperpolarizability using solvatochromic shift method. These dyes show high first hyperpolarizability in the range of 39.96-296.35 x 10(-30) esu by theoretical method and 35.8 -302 x 10(-30) esu by solvatochromic shift method. (C) 2015 Elsevier Ltd.
