520 $a An exciting new class of metallacycle (eta5-C5 H4Fe) (CO)2CH2SiR2 that undergoes ring-opening polymerization was recently reported by Sharma et al. [1]. We are interested in further expanding this research area by synthesizing related cyclopentadienyl derivatives containing Fe, Mo, and W in combination with other elements of the group 14. We report here the synthesis and crystal structure characterization of new germa-metallacyclobutanes of Mo and W. In addition, we have successfully synthesized and characterized new ring-opening polymers of the related germanium systems [(eta5-C5 H4Fe)(CO) 2(CH2GeR2)] n. The new polymers were characterized using various spectroscopic techniques and gel permeation chromatography.
520 $a The recent report on the synthesis of a new class of siloxane polymers based upon base-catalyzed ring opening of phenylene-bridged cyclic siloxanes [2] encouraged us to investigate the related ferrocenyl (Fc, (C5H 5)Fe(C5H4)) siloxane systems. The incorporation of ferrocene could provide new materials with all the interesting properties usually associated with these groups such as thermal and photochemical stability, electrochemical activity and potentially conducting materials. Thus far a new required organometallic monomer containing Fc-R, where R = disilaoxacyclopentene 5 has been synthesized and completely characterized. Based-induced ring-opening polymerizations of 5 were attempted under different reaction conditions and produced, inter alia: (C5H5)Fe(C 5H4)C(SiMe2OH)=CH(SiMe2R), R = nBu (2), tBu (3), Ph (4). The single crystal X-ray structures and full spectroscopic analysis of such products has been accomplished. Furthermore, the reactivity of the ferrocenyl silanols concerning condensation and their behavior under acidic conditions has been investigated.
