| abstract | 1,255,786. Unsaturated sulphonyl compounds. EASTMAN KODAK CO. 8 Nov., 1968 [13 Nov., 1967], No. 63119/68. Heading C2C. [Also in Division G2] HOCH 2 CH 2 SNa is reacted With CICH 2 CH 2 - OCH 2 CH 2 Cl to give (HOCH 2 CH 2 SCHCH 2 ) 2 O which is then oxidized with H 2 0 2 to (HOCH 2 - CH 2 SO 2 CH 2 CH 2 ) 2 0 which is in turn treated with SOCl 2 to give (ClCH 2 CH 2 SO 2 CH 2 CH 2 ) 2 0 which is dehalogenated with Et 3 N in tetrahydrofuran to give (CH 2 = CHSO 2 CH 2 CH 2 ) 2 0. (ClCH 2 CH 2 SO 2 CH 2 CH 2 CH 2 CH 2 ) 2 O and (CH 2 CHSO 2 CH 2 CH 2 CH 2 CH 2 ) 2 0 are prepared similarly. (CH 2 = CHSO 2 CH 2 CH 2 ) 2 NCH 2 CH 2 CH 3 is prepared from CH 2 = CHSO 2 CH = CH 2 and CH3- CH 2 CH 2 NH 2 . The vinylsulphonyl compounds are used as photographic hardeners. |
