| Nucleophilic substitution on O-alkyl-4-chlorobenzohydroximoyl fluorides (ClC6H4C(F)=NOCH3 (1) and ClC6H4C(F)=NOCH(CH3)2 (2)] by enolate anions and Grignard reagents have given the following O-alkyl oximes (3-8): [ClC6H4CCH(CN)2=NOCH3 (3), ClC6H4CCH(CN)(CO2Et)=NOCH3 (4), ClC6H4CCH(CO2Et)2=NOCH3 (5), ClC6H4C(CH3)=NOCH(CH3)2 (6), ClC6H4C(C6H5)=NOCH(CH3)2(7), and ClC6H4C(C6H5CC)=NOCH(CH3)2 (8)]. An X-ray crystallographic analysis of 4 has shown that the compound exits in the enamine tautomer in the solid state. The 13C-NMR spectrum of 4 indicates that it is a mixture of the enamine and imine tautomers in CDCl3.
