Abstract
The acid-catalyzed polycondensation of ferrocenylphenylcarbinol Ic under controlled, mild reaction conditions gives rise to the formation of low-molecular, ferrocene-containing polymeric ethers, to which, on the basis of elemental analysis, infrared and NMR spectro-scopic data, the structure IIIf is assigned. Monomeric ether IIIc is isolated in addition under these conditions. In the presence of Lewis acids at elevated temperatures, ethers Illf continue to react, with the elimination of the ether bridge, to give polymers identical with the previously reported oxygen-free compounds IIc, which were obtained directly from Ic under more rigorous conditions. In the previous work, polymers IIIf containing an ether group were postulated as intermediates but were not isolated. The observed formation of such polymers under the present experimental conditions, coupled with their successful post-condensation to IIc, is thus in accord with the earlier mechanistic implications.This publication has 2 references indexed in Scilit:
