An efficient synthesis of a series of pyrazolopyridocoumarins is reported by condensation of 4- hydroxycoumarin, benzaldehydes and 1-alkyl-5-amino-pyrazoles in the presence of 10 mol% zinc chloride in ethanol under reflux conditions through one-pot reaction. The significant attraction of this protocol is being a simple procedure, mild reaction condition, and excellent yield. The molecular structure of the compound (4e) is established by single crystal X-ray structure determination. Keywords.

  • Growth and Characterization of a New Non-Linear Optical Crystal: Urea Thiourea Zinc Chloride
    Asian Journal of Chemistry Vol. 20, No. 7 (2008), 5067-5070 Growth and Characterization of a New Non-Linear Optical Crystal: Urea Thiourea Zinc Chloride G. MADHURAMBAL† and M. MARIAPPAN* Department of Chemistry, R.V.S. College and Technology Kallikuppam, Thiruvettakudi Post, Karaikal-609 609, India E-mail: [email protected]; [email protected] Urea thiourea zinc chloride (UTZC) a new semi-organic non-linear optical material has been synthesized. Single crystals of UTZC have been grown by slow evaporation of saturated aqueous solution at room temperature. The spectral bands have been compared with urea, thiourea, bis thiourea zinc chloride (BTZC). Key Words: Urea thiourea zinc chloride crystals, Non- linear optical material. INTRODUCTION Non-linear optics playing a vital role in the emerging photoelectronic technologies. New non-linear optical (NLO) frequency conversion materials have a significant impact on laser technology, optical communication and optical data storage. The search for new and efficient NLO materials has resulted in the development of a new class of materials called semi-organics. These materials have the potential for combining the high optical non- linearity and chemical flexibility of organic materials with the thermal stability and mechanical robustness of inorganic NLO materials1. Thiourea possess a large dipole moment and it forms a number of co-ordination compounds like bis thiourea cadmium chloride (BTCC)2 and tris thiourea zinc sulphate (ZTS)3, antimony thiourea bromide monohydrate (ATBM)4 which are potential materials for frequency doubling of the near IR laser radiation. Single crystals of these materials have very high laser damage threshold5. In general crystals of the type M[tu]2X2, where M = Cd, Co, Hg, Pb, Ti, Zn; tu = thiourea and X = halogen, have been found to exhibit good NLO proper- ties6.
