Only mononuclear Ni(II) and Co(III) complexes with a metal : ligand ratio of 1 : 2 were isolated. These hydrogen-bridged complexes were converted to their analogues by reaction with boron triÑuoride etherate. The reaction of the BF 2 `-bridged BF 2 `-bridged complexes with Pd(II) and Ni(II) gave heterotrinuclear complexes. These compounds are signiÐcant in that they provide binding sites not only within but also outside the macrocycles. Structures for the dioxime and its complexes are proposed in accordance with the elemental analysis, 1H and 13C NMR, IR and mass spectral data, magnetic susceptibility measurements and semi-empirical quantum chemical calculations.

The presence of substituents in cyclohexane can influence to the ratio of conformers; for some cases, the boat form is preferable. The new six-membered cyclohexanol derivative 2 has been obtained by the synthesis of (E)-1-(bromophenyl)-3-phenylpropen-2-one (1). The NMR and quantum-chemical conformational analysis for the 2 have carried out, and its possible mechanism of formation was given. Copyright © 2015 John Wiley & Sons, Ltd.
