"The electronic parameters of 25 Werner-type and organometallic ligands have been experimentally determined and ranked on a unprecedented unified C-13 NMR scale using safe and easily obtainable complexes of the type trans-[(PdBr2)-Pd-i(Pr-i(2)-bimy)L]''(-) (Pr-i,-bimy = 1,3-diisopropylbenzimidazolin-2-ylidene; L = ligand in question) as spectroscopic probes. The methodology is based on the sensitivity of the constant (i)Pr2-bimy carbene signal to the donor strengths of the varying co-ligands, which even allows detection of backbone and substituent effects more accurately than previous carbonyl-based systems," investigators in Singapore, Singapore report.
"For ...
