✦ Synopsis

Several authors have utilized 13 C NMR spectroscopy (CMR) for the investigation of 1 organo-transition metal x-complexes . In the field of organosilver complex chemistry t some 2 CMR measurements have been reported recently by Parker and Roberts . Comparing the CMR spectra 'The saturated carbon atoms are generally shifted downfield upon coordination in the range O-5 Hz in methanol and O-20 Hz in chloroform. d Complex formation of ethylene with silver nitrate and tetrafluoroborate in methanol and with silver tetrafluoroborate in chloroform (saturated solutions) resulted in an upfield shift.
