A simple procedure for SnCl(2)/TiCl(3)-mediated deoximation of ketoximes in an aqueous solvent is reported. Under the conditions developed in this effort, various ketones and aldehydes are produced in good to excellent yields.

Following our previous studies on potassium poly(heptazine imide) (K-PHI), that is, catalyzed photooxidative [3+2] aldoxime-to-nitrile addition to form 1,2,4-oxadiazoles, we discovered electron-rich oximes yield the parent aldehydes instead of target products. In this work, mechanism singlet oxygen-mediated deoximation process was established using a series control reactions and spectroscopic m...
