Cyclopalladation of the Schiff bases of general formula McCH N–CH(Me)Fc (Mc Fc, Ru) (1a,b) with a chiral centre leads to the mixtures of three products, two of which (2 and 3) are planar chiral diastereomers formed from homoannular substitution int

Two-step synthesis of 1,1’-di(α-dimethylamino)ethylferrocene is described in details. Cyclopalladation of this diamine involving one or two amino groups is reported and the product of asymmetric mono-cyclopalladation is fully characterized. Keywor

The formation of a new chiral center in the reactions of ketone 4-MeOC6H4CH(Et)C(O)Et with planar-chiral 2-lithio-1-methyl- and 1-chloro-2-lithioferrocenes proceeded stereoselectively to give two diastereomers in a ratio of ∼3 : 2 or a single diast

Hydroxyferrocene (ferrocenol), a metallocene analog of phenol, has been converted into a phosphite ester with chiral (racemic) butane-1,3-diol which undergoes cyclopalladation similarly to hydroxyarene phosphites. In this case, a planar chirality eme
