Microwave-assisted additive free synthesis of nanocrystalline zinc oxide
No full textAn additive free synthesis of nanocrystalline zinc oxide using microwave technique is reported. Current methodology is faster, cleaner and cost effective compared with conventional method for the synthesis of zinc oxide nanocrystalline materials. The structure and morphology of nanocrystalline zinc oxide was investigated by TEM, XRD, EDAX, UV-Vis spectroscopy. The results demonstrate that microwave heating can produce polygonal zinc oxide within a short span of time

No full textA carbon-monoxide-free aminocarbonylation of various N-substituted formamides with aryl iodides and aryl bromides using palladium acetate and Xantphos is described. The developed methodology is applicable for a wide range of formamides and aryl halides containing different functional groups furnishing good to excellent yield of the corresponding products. N-substituted formamides are used as an amide source wherein a Vilsmeier-type intermediate plays a major role, thus eliminating the need of toxic carbon monoxide gas
