Abstract

Dimeric [Ti(O__i__Pr)~2~(benzaldoximate)~2~]~2~ was obtained upon reaction of titanium isopropoxide with two molar equivalents of benzaldehyde (E)‐ or (Z)‐oxime or m‐anisaldoxime. Two isomers were formed differing by the mutual orientation of the oximate ligands. Reaction with perillaldoxime or trans‐cinnamaldoxime resulted in the corresponding derivatives with functional ligands. The degree of substitution was higher when o‐ or p‐anisaldoxime were employed in the same molar ratio, and dimeric Ti~2~(O__i__Pr)~3~(o‐anisaldoximate)~5~ with a bridging oximate ligand and monomeric Ti(oximate)~4~ (oximate = o‐anisaldoximate or p‐anisaldoximate) were obtained. Dissolution of the p‐anisaldoximate derivative upon heating in [D~6~]DMSO led to deoximation reactions.

The ring-opening of functionalized epoxides with trimethylsilyl azide in the presence of a catalytic amount of Ti(O-i-l%)4 or Al@-i-F?)3 is described. The reaction is stereo8pecific and highly regiospecific, leading generally to the formation of the carbon-azido bond on the less substituted carbon.
