INTRODUCTION Pinacol coupling was first described by Fittig in 1859, when he reported the formation of 2,3dimethyl-2,3-butanediol (1) from acetone and sodium metal. Since then, this ketyl radical anion coupling process has undergone significant advancement, including the development of asymmetric variants. 3 Alternatives to use of strong reducing metals are low valent transition metals and lant...

Oximes are highly crystalline materials and oximation is very efficient method for characterization and purification of carbonyl compounds. These compounds not only represent a useful series of derivatives of carbonyl compounds but also may be used as intermediates for the preparation of amides by the Beckmann rearrangement [1], nitrones [2], hydroximinoyl chlorides, nitrile oxide [3] and chi a...
