ORGANOGERMANIUM POLYMER SYNTHESIS FROM SUBVALENT GERMANIUM COMPOUNDS

摘要

Several organogermanium polymers containing germanium atom in the polymer chain were synthesized by using a subvalent germanium compound (germylene) as a monomer or a comonomer. The polymers were characterized by using ~1H and ~(12)C NMR as well as GPC. Germylenes have a similar structure as carbenes and silylenes , but can exist as stable species at ambient temperatures. Germylene chemistry is a latecomer in organometallic chemistry, most of the research works started Just from the early 1970's. The first "stable" germylene was appeared in 1974. while polymer synthesis by using the high reactivity of germylenes was just the things in recent couple of years. Here we report our some new findings in this field of study.
