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.
