Autor: K. Ranganathan, R. Suresh, G. Vanangamudi, K. Thirumurthy, P. Mayavel, G. Thirunarayanan

Publikováno v: Bulletin of the Chemical Society of Ethiopia, Vol 28, Iss 2, Pp 271-288 (2014)

Some aryl-aryl 1H pyrazoles have been synthesised by cyclization of aryl chalcones and hydrazine hydrate in the presence of SOCl2. The yields of the pyrazoles are more than 85%. These pyrazoles are characterized by their physical constants and spectr

Kinetic Studies on the Oxidation of Some para and meta-Substituted Cinnamic Acids by Pyridinium Bromochromate in the Presence of Oxalic Acid (A Co-oxidation Study)

Autor: G. Vanangamudi, S. Srinivasan

Publikováno v: E-Journal of Chemistry, Vol 6, Iss 3, Pp 920-927 (2009)

The kinetics of oxidation of cinnamic acids by pyridinium bromochromate (PBC) in the presence of oxalic acid has been studied in acetic acid-water (60:40%) medium. The reaction shows unit order dependence each with respect to oxidant as well as oxali
