Abstract: Photoacid generators generate sulfonic acids of formula (1a) or (1c) upon exposure to high-energy radiation. R1—COOCH(CF3)CF2SO3+H+??(1a) R1—O—COOCH(CF3)CF2SO3?H+??(1c) R1 is a C20-C50 hydrocarbon group having a steroid structure. The photoacid generators are compatible with resins and can control acid diffusion and are thus suited for use in chemically amplified resist compositions.

Abstract: The invention relates to a low-pressure discharge lamp with at least one porting element (12) placed inside a discharge vessel (10). Said supporting element is provided with a mercurial coating (13) and is coated with a getter material (14). The coated surfaces of the supporting element (12) are inclined at an angle of at least 30 degrees in relation to the longitudinal axis (A--A) of the discharge vessel (10).

Abstract: The present invention relates to a method of using a perchloric acid catalyzed reaction to make acyl derivatives of norprogesterone compounds and, in particular, 16-methylene-17.alpha.-hydroxy-19-norpregn-4-ene-3,20-dione.

Abstract: New 9-alpha-hydroxy steroids are prepared by the introduction of substituents on the D-ring of 9-alpha-hydroxy-androst-4-ene-3,17-dione.The resulting compounds are useful intermediates in the synthesis of corticosteroids.

Abstract: Novel steroids having a 9.alpha.-hydroxy or a 9.alpha.-carbonate substituent can be prepared from 9.alpha.-hydroxyandrostenedione and can be utilized in the synthesis of commercially valuable corticosteroids such as betamethasone. The 9.alpha.-carbonates are prepared by reaction of the corresponding 9.alpha.-hydroxy steroid with a sequence of excess base, trialkylsilyl chloride, alkyl haloformate and alkanol or by using excess base, alkyl haloformate and alkoxide. 9.alpha.-Carbonate-17-keto compounds can be treated with lithium acetylide and a lithium salt to afford the corresponding 17.alpha.-ethynyl-17.beta.-hydroxy-9.alpha.-carbonate. This compound is then esterified with a novel series of reagents to give the 17-ester which can be reduced the corresponding 17-allene. Oxidation of this allene to the bis-epoxide compound, followed by treatment with an alkali metal salt of a carboxylic acid under phase transfer conditions gives the 17.alpha.-hydroxy 21-ester 9.alpha.-carbonate. Elimination of the 9.alpha.
