Abstract

Hydridosilapyrroles and hydridosilaazapyrrole are a new class of heterocyclic compounds having a silicon bound to carbon and nitrogen atoms within the ring system and one or two hydrogen atoms on the silicon atom. The compounds have formula (I): in which R is a substituted or unsubstituted organic group and R′ is an alkyl group. These compounds react with a variety of organic and inorganic hydroxyl groups by a ring-opening reaction and may be used to produce silicon nitride or silicon carbonitride films.

Claims (5)

1. A hydridosilapyrrole having formula (I):

wherein R is an alkyl, aryl, ester, chiral phenethylamine, trimethylsilyl, or tertiary amine group and R′ is an alkyl group containing 1 to about 20 carbon atoms.

2. The hydridosilapyrrole according to claim 1 , wherein the hydridosilapyrrole is N-butyl-2-silapyrrole.

3. The hydridosilapyrrole according to claim 1 , wherein the hydridosilapyrrole is N-(3-dimethylaminopropyl)-2-silapyrrole.

4. The hydridosilapyrrole according to claim 1 , wherein the hydridosilapyrrole is (N-trimethylsilyl-2-methyl-silapyrrole).
