The Coumarine heterocyclic ring is common feature of various bioactive compounds such as calanolides, lipid-lowering agents. The Chemists all over the globe are motivated not only for the environmentally benign synthesis of new products but also to develop green synthesis for existing chemicals. Coumarins, the most important classes of fluorescent molecules constitute important structural featu...

The high yield electrophilic substitution procedure for the synthesis of bis indolyl methanes at room temperature has been carried out effectively by using a novel metal supported organo catalyst. advantages this method include simple conditions, great yields, less work-up, an environmentally friendly process and reusable solid Several were synthesised confirmed IR, H1 13C NMR techniques. Catal...

UNLABELLED BACKGROUND Green catalyst fly ash: H2SO4 was prepared by mixing fly ash and sulphuric acid. Microwave irradiations are applied for solid phase cyclization of 5-bromo-2-thienyl chalcones and phenyl hydrazine hydrate in the presence of fly ash: H2SO4 yields, 1-phenyl-3(5-bromothiophen-2-yl)-5-(substituted phenyl)-2-pyrazolines. These pyrazolines were characterized by their physical ...

The accelerated UV visible photocatalytic carbon-carbon double bond isomerization of Linear Alpha Olefins (LAO) with 12-Tungstophosphate Acids (12-TPA) as an efficient, environmentally-friendly and recyclable catalyst was described, which produced the corresponding Internal (LIO) in general high selectivity yields.

a simple, clean, and environmentally benign three-component process for the synthesis of 2-amino-4hchromenes using [mim]cl, as an efficient catalyst under solvent-free conditions are described. a wide range of aromatic aldehydes easily undergoes condensations with 1-naphthol and malononitrile under solvent-free conditions to afford the desired products of good purity in excellent yields. taking...

sulfated titania nanoparticles (so42-/tio2 nps) were synthesized using titanium tetraisopropoxide (ttip) by the sol-gel method. the structure and morphology of the prepared nanocatalyst was characterized using x-ray diffraction (xrd), scanning electron microscopy (sem) and brunauer–emmett–teller (bet) methods as well as fourier transform infrared (ft-ir) and energy dispersive x-ray (edx) spectr...
