Silver complexes halogen donors

With this type of shift reagent, the silver ion binds to soft Lewis base donors, such as olefins, aromatics, phosphenes, and halogenated compounds. At the same time, silver remains as an ion pair with Yb(fod)4 in a specific orientation such that a paramagnetic shift is induced in the resonances of the organic soft base. This method has proven to be useful for the separation of NMR resonance peaks of cis and trans geometric isomer mixtures of long-chain alkenes and complex mixtures of aromatic molecules [5]. [Pg.783]

Note The polymeric nature of these silver(I) bis-carbene complexes limits their solubility in most organic solvents including the standard CH Cf. Strong donor solvents like DMSO overcome this problem, probably by breaking the silver-halogen bridges. [Pg.135]
