SDS of cas: 93-02-7. Recently I am researching about MULTICOMPONENT REACTIONS; BIOLOGICAL EVALUATION; TRANSPORTING MATERIAL; DERIVATIVES SYNTHESIS; FLUORESCENCE SENSOR; ORGANIC-SYNTHESIS; BLUE FLUORESCENT; HOLE-TRANSPORT; DESIGN; MOLECULES, Saw an article supported by the Council of Scientific and Industrial Research (CSIR), New Delhi, Government of IndiaCouncil of Scientific & Industrial Research (CSIR) – India [01 (2391)/10/EMR-II]; Department of Atomic Energy-Board of Research in Nuclear Sciences (Bhabha Atomic Research Centre), Mumbai, Government of India [2011/37C/52/BRNS/2264]. Published in ROYAL SOC CHEMISTRY in CAMBRIDGE ,Authors: Godugu, K; Gundala, TR; Bodapati, R; Yadala, VDS; Loka, SS; Nallagondu, CGR. The CAS is 93-02-7. Through research, I have a further understanding and discovery of 2,5-Dimethoxybenzaldehyde
A water-mediated MCR strategy has been developed for the synthesis of donor (D)-acceptor(A) type hydrazinyl thiazolyl coumarins (HTCs) (4) in excellent isolated yields (90-98%) from a three component reaction of aromatic aldehydes/ketones (1), thiosemicarbazide (2) and 3-(2-bromoacetyl)-2H-chromen-2-one (3) catalyzed by an environmentally compatible montmorillonite (MMT) K10 clay at RT for 20-40 min. The present MCR strategy has several advantages that include its wide-spread substrate scope, eco-compatibility, short reaction times and products that do not require chromatographic purification. Besides, the method is simple to perform, it is easy to construct C-N, C=N and C-S bonds in one pot and the reaction can be scaled up to a gram level. Moreover, the catalyst can be reused 7 times without significant change of activity. The photophysical properties of the synthesized D-A type HTCs are also studied and it was noticed that the fluorescence properties can be varied with the position of electron donating group on the aromatic ring of aldehyde/ketone of HTCs. Most of the compounds exhibited bright fluorescence in chloroform (1.0 x 10(-5) M) with emission maxima ranging from 409 to 511 nm and large Stokes shifts. Further, the HOMO and LUMO energy levels of the HTCs are found in the range from -5.65 eV to -5.22 eV and -2.67 eV to -2.17 eV, respectively, and in good agreement with the reported hole transporting materials.
