Abstract

By the reaction of 1,1' -diacetylferrocene with diethyl oxalate,
y,y'-(1,1'-ferrocenylene) -bis(a,y-dioxobutyric acid) (I) and its diethyl
ester II were prepared in yields of 52 and 540/o respectively.
The polyoxo compounds I and II were converted by the action
of suitable reagents into 1,1' -bis[3(5)-carboxyhydrazido-5(3) pyrazolyl]
ferrocene (III), 1,1' -bis [3(5)-carbethoxy-5(3)-pyrazolyl]ferrocene
(IV), 1,1' -bis[2-oxo-3-piperazinylideneacetyl]ferrocene
(V), 1, l' -bis[3(5)-carbethoxy-1-phenyl-5(3)-pyrazolyl] ferrocene (VI)
and 1,l'-bis[3(5)-carbethoxy-5(3) -isoxazolyl]ferrocene (VII).
