Sažetak

Reaction of several a-substituted ferrocenylmethanols 1 with diethyl malonate gave condensation products 3, which were hydrolized and decar- boxylated to p-ferrocenylbutyric acid (6a) and p-aryl-p-ferrocenylpropionic acids (6b-6e). Similarly, starting from a,a'-disubstituted l,l'-ferrocenylene- bismethanols 2 p,p-(l,l'-ferrocenylene)bis(butyric acid) (11a) and P,P-(1,1'- ferrocenylene)bis(p-arylpropionic acids) (llb-lle) have been obtained via 8 and 9. The mechanism of these condensation reactions which includes transesterification of diethyl malonate with carbinols 1 and 2 has been proposed.
