CYCLOPALLADATION OF SCHIFFS-BASES IN THE RUTHENOCENE SERIES - THE POSSIBILITY OF APPLICATION OF THE ASYMMETRIC VERSION OF THE REACTION TO METALLOCENEIMINES

p-Tolyliminoalkylruthenocenes - Schiff's bases of the ruthenocene seri es - react with. sodium tetrachloropalladate in the presence of carbox ylate anion similarly to their ferrocenyl analogs to give cyclopallada tion products. The optical rotation values of the products resulting f rom carbonylation of palladated ferrocene and ruthenocene aldimines, p repared under conditions of asymmetric catalysis, followed by liberati on of the aldehyde group were used to determine the stereochemistry an d enantiomeric purity of the cyclopalladation products.
