Abstract: Abstract While several methods are available for the synthesis of a host of trifluoromethylated heterocycles, very few of them have been applied to access 4-trifluoromethylated 1,2,3-triazoles. We report herein a general methodology for the trifluoromethylation… read more here.

Abstract: Abstract We have developed an effective and environmentally benign procedure for the hydroxylation of naphthoquinone derivatives by using tetrabutylammonium iodide as a catalyst and tert-butyl hydroperoxide as an oxidant. This methodology provides a facile protocol… read more here.
