✦ Synopsis
Stereoselective nucleophilic substitution reactions at spz hybridised carbon in vinyl systems proceed generally with retention of configurat.lon.' One example of a stereospecific bimolecular nucleophilic displacement at an imino carbon has been reported by Johnson, Nally and Weidiy;' usir; g methoxide ion as nucleophile, (El-0-methylbenzoh$&oximoyl chloride wa$: converted to methyl-(Z)-0-methylbenzhydroximate with inversion of confiiguration. This result cannot be general, however, since we now report a bl-C=NIN/Me \ 3
