Abstract
We describe an effi cient methodology for t he preparat ion of n ew c hiral z inc c omplexes by assembling dynamically racemic biphenol derivatives and chiral 1,2-diamines with suitable zinc(II) precurs or s. M o no nu c le a r a nd d in u cl e a r z in c ( II ) c om pl e xe s we r e formed from di fferently substituted biphenols. The solid-state and solution structural characterizat ion o f the resulting compounds allowed us to d emonstrate a preferential sense of induced axial chirality for mono-nuclear complexes, a phenomenon that was not observed for the dinuclear onesFile in questo prodotto:
