FLUORINATED SULFONATE ESTERS OF ARYL KETONES FOR NON-IONIC PHOTO-ACID GENERATORS

Non-ionic photo-acid generating (PAG) compounds were prepared that contain an aryl ketone group having a perfluorinated substituent alpha to the ketone carbonyl. The non-polymeric PAGs release a sulfonic acid when exposed to high energy radiation such as deep UV or extreme UV light. The photo-generated sulfonic acid has a low diffusion rate in an exposed resist layer subjected to a post-exposure bake (PEB) at 100° C. to 150° C., resulting in formation of good line patterns after development. At higher temperatures, the PAGs can also undergo a thermal reaction to form a sulfonic acid. The perfluorinated substituent provides improved thermal stability and hydrolytic/nucleophilic stability.

Metal-free [2 + 2 + 1] annulation of alkynes, nitriles, and oxygen atoms: Iodine(III)-mediated synthesis of highly substituted oxazoles

The metal-free [2 + 2 + 1] annulation of alkynes, nitriles, and O-atoms for the regioselective assembly of 2,4-disubstituted and 2,4,5-trisubstituted oxazole compounds has been achieved by the use of PhIO with TfOH or Tf 2NH. The present reaction could be applied to a facile synthesis of an anti-inflammatory drug.
