Template synthesis, structure and properties of 4-pyridinylboron-capped iron(II) clathrochelate precursors for Bubnov diallylation reaction

First 4-pyridinylboron-capped iron(II) clathrochelates, which are prospective both the precursors for Bubnov diallylation reaction and the bridging ditopic N,N′-ligands for design of coordination polymers and polynuclear transition metal complexes, were obtained by template macrobicyclization of aliphatic, aromatic and halogenide α-dioximes with 4-pyridinylboronic acid on a Fe2 + ion as a matrix.
