The development of an environmentally benign sulfide oxidation procedure and its assessment by green chemistry metrics
(Royal Society of Chemistry, 2009-02)
Different Iron (III) species were used as catalysts in sulfoxidation reactions giving excellent yields and high chemoselectivity. Among the iron (III) species, the best one was a solid β-cyclodextrin-FeBr3 complex. ...
New Mixed Li/Mg and Li/Mg/Zn Amides for the Chemoselective Metallation of Arenes and Heteroarenes
(WILEY-V C H VERLAG GMBH, 2009)
New mixed Li/Mg and Li/Mg/Zn amides have been synthesized starting from readily prepared secondary amines. They allow a highly chemoselective directed magnesiation or zincation of various polyfunctional aromatics and ...
