Onium salt compound, resist composition, and pattern forming process

Sulfonium and iodonium salts of a carboxylate having an aromatic ring to which a nitrogen-containing alkyl or cyclic structure is attached are novel. The onium salt functions as an acid diffusion controlling agent in a resist composition, enabling to form a pattern of good profile with high resolution, improved MEF, LWR and DOF.

SYNTHESIS OF ACYCLIC AND CYCLIC AMINES USING IRON-CATALYZED NITRENE GROUP TRANSFER

The present invention provides novel synthetic methods for making acyclic secondary amines by reacting an azide with a compound bearing one or more CH groups, catalyzed by a Fe.sup.II-dipyrromethene complex. The acyclic secondary amines are thought to be formed through an intermolecular nitrene transfer. Also provided herein are methods of synthesizing protected (e.g., Boc- or Fmoc-protected) cyclic secondary amines (e.g., 5-, 6-, and 7-membered cyclic secondary amines) by reacting an azide that bears one or more CH groups, catalyzed by a Fe.sup.II-dipyrromethene complex. The protected cyclic secondary amines are thought to be formed through an intramolecular nitrene transfer and may be subsequently deprotected to yield cyclic secondary amines.
