Polymers Containing Oxygen, Nitrogen, Silicon, and Sulfur in the Backbone

POLYMERS CONTAINING OXYGEN, NITROGEN, SILICON, AND SULFUR IN THE BACKBONE 

A wide variety of Ge-O, Ge-N, Ge-Si, and Ge-S polymers have been synthesized. Some of these wiU be reviewed here. 

In addition, analogous ferrocene products, 75, were synthesized, where the R in 73 is a 1,1 -ferrocene unit. Product yields were about 50% the reaction is completed within several seconds. 

Other Group IVA oligomeric ferrocenyl polymers were made. In general, yields decrease as the complexity of the aliphatic substituent on the Group IVA metal increases yields also decrease in the order Sn Ge Si and I Br Cl. 

This approach has been expanded to the synthesis of other materials, for example, 79 and 80 While the product structures appear similar with respect to reactants, the mechanisms offered to transverse this journey are varied.
