Abstract

Transition-metal complexation effects which can be observed in 13C NMR spectra have been investigated for the (η6-cyclophane)(η6-benzene)ruthenium(II) bis(tetrafluoroborate) complexes, where the cyclophane moiety is [8]-[15]paracyclophane, [2.2]paracyclophane, [2.2]metacyclophane or 5,13-dimethyl[2.2]metacyclophane. The complexation shifts for the complexed cyclophane-ring carbons are dependent on the degree and direction of ring bending. The magnitude of the complexation effect on the one-bond aromatic 13C1H coupling correlates with the magnitude of the complexation shift.
