SYNTHETIC COMMUNICATIONSp 19(19) 3385-3395 (1989) Selective Oxidative Cleavage of Benzylic Carbon- Nitrogen Double Bonds under Non-Aqueous Condition with Tetrakis(pyridine)- silver Dichromate [ CPY) pg 1 2 Cr207 H. Firouzabadi*, M. Seddighi, Z.Arab Ahmadi A.R. Sardarian Department of Chemistry Shiraz University, Shiraz, Iran. Summary: Carbonyl derivatives of phenylhydrazine, 2-nitrophenylhydrazine, 2,4-dinitrophenylhydrazine,' semicarbozone, and hydroxylamine are converted to their corresponding carbonyl compounds with tetrakis(pyridine)silver dichromate in benzene. Selectivity is also observed for benzylic C = N cleavage. 3385 Copyright 0 1989 by Marcel Dekker, Inc.
