In one aspect, the present invention provides catalysts for the carbonylation of heterocycles. The inventive catalysts feature metal-ligand complexes having cationic functional groups tethered to the ligand, wherein the tethered cationic groups are associated with anionic metal carbonyl species. The invention also provides methods of using the inventive catalysts to affect the ring opening carbonylation of epoxides.

Catalytic carbonylation catalysts and methods

A polycarbonate polymer such as poly(cyclohexene carbonate) acts as a positive electron beam resist, is substantially transparent to ultra violet light and that depolymerizes when heated. The polymer acts as a positive electron beam resist at 5 kV, and depolymerizes at temperatures between approximately 200-300&deg; C. The polymer is removable from underneath other layers by heating, facilitating fabrication of overhanging structures such as tubes by depositing layers on top of the polymer.
