摘要:
Fluorine-free photoacid generators and photoresist compositions containing fluorine-free photoacid generators are enabled as alternatives to PFOS/PFAS photoacid generator-containing photoresists. The photoacid generators are characterized by the presence of a fluorine-free heteroaromatic sulfonate anionic component. The photoacid generators preferably contain an onium cationic component, more preferably a sulfonium cationic component. The photoresist compositions preferably contain an acid sensitive imaging polymer. The compositions are especially useful for forming material patterns using 193 nm (ArF) imaging radiation.

PROBLEM TO BE SOLVED: To provide a gentle to environment method for producing 2- nitrothiophene from thiophene in 100% selectivity and in a high yield by using a metal ion-exchanged clay catalyst and nitric acid without using acetic anhydride. SOLUTION: This method for producing 2-nitrothiophene is provided by nitrating thiophene by using nitric acid in the presence of a solid acid catalyst selected from a montmorillonite clay catalyst and metal ion-exchanged K10 montmorillonite clay catalyst, and recovering 2-nitrothiophene by concentrating the reaction mixture after separating the catalyst.

摘要:
A compound represented by general formula (I), a pharmaceutically acceptable acid addition salt thereof or a pharmaceutically acceptable C1-C6 alkyl addition salt thereof, and their medical applications. Since these compounds inhibit the action of chemokines such as MIP-1 alpha and/or MCP-1 on target cells, they may be useful as a therapeutic drug and/or preventative drug in diseases, such as atherosclerosis, rheumatoid arthritis, and the like where blood monocytes and lymphocytes infiltrate into tissues.
