Functionally substituted organotin compounds

The structures of the oximes formed from (4-oxopentyl)triphenyltin and (4-oxopentyl)diphenyltin chloride have been determined using IR, PMR and Mossbauer spectroscopy. Beckmann rearrangement of (4-oximinopentyl)diphenyltin chloride with phosphorus pentachloride gave the amide resulting from exchange of null syn null groups. Treatment of the second oxime with phosphorus pentachloride caused other reactions but the null O -tosyl derivative was...
