Tris-dioximate rhenium(III) semiclathrochelates underwent reduction domino-reactions.
These ligand-centered reactions gave the reduced diimine-iminoximate derivatives.
Template condensation on Re3 + ion afforded its formylphenylboron-capped tris-dioximate.
This semiclathrochelate undergoes a further H+-catalyzed condensation with isoniazid.
The obtained semiclathrochelate hydrazone contains an apical vector substituent.
