Ketoximes undergo facile deprotection in acetone-H20 (9: 1) in the presence 01' 0.5 equivalents of Bi(N03h·5H20. Bis muth(lII) nitrate is relatively non-toxic, insensitive to air and inex pensive. These features coupled with the use of a relatively non toxic solvent system make this method an attractive alternative to existing routes for deprotection of ketoximes.
