Transition metal–carbon bonds. Part XXXIV.1H and13C nuclear magnetic resonance studies on π-allylic–palladium complexes

Abstract
Under high resolution the 1H n.m.r. spectra of π-allylic–palladium compounds are more complex than previously reported :e.g., the resonance of the central allylic hydrogen of [Pd2I2(C3H5)2] consists of 15 ‘lines’. The spectra are thus interpretable as AA′BB′C patterns. Some relative signs of coupling constants in π-allylic complexes are reported for the first time. 13C N.m.r. spectral shifts and J(13C1H) values are reported and discussed. [Pd(acac)-(1,2,3,7-cyclo-octa-2,4-dienylpalladium] is shown not to be fluxional at 25° by 13C n.m.r. spectroscopy.
