Novel NЈ-methylated 2-(oxazolin-2-yl)-4,4Ј-bipyridinium salts, bearing a chiral oxazoline moiety, were tested in the Rh(I)-catalysed enantioselective hydrosilylation. After coordination to rhodium these electron-attracting ligands are supposed to exhibit charge-transfer effects with electron-donating substrates. Therefore, a new catalytic hydrosilylation

Novel 2-(4,4'-bipyridin-2-yl)oxazolines, bearing a chiral oxazoline moiety, were synthesised starting from 4,4'bipyridine and selectively monomethylated in the N'position. After coordination to rhodium these electron-poor ligands are supposed to exhibit charge-transfer effects with electron-donating
