carbamoyloxime acetylcholinesterase inhibitors, a straight-forward approach to estimating pKa values of a series of precursor oximes and thiohydroximates has been developed. The pKa values of oximes correlate well with the protonchemicalshifts of the oximino proton (delta OH) in dilute dimethyl sulfoxide-d6 solution. The relationship pKa = 29.10 - 1.63 delta OH was developed from delta OH and pKa data for 20
