| abstract |
Triiodophenyl compounds (I) are new. They are prepared e.g. by reaction of the corresponding amine with an acid chloride. Triiodophenyl compounds of formula (I) and their salts with inorganic and/or organic bases, amino acids and amides are new. R1, R2 = H, COOH, CONR3R4 or NR5COR6, provided that both R1 and R2 are not H; R3, R4 = H or 1-6C alkyl which is optionally substituted by 1-5 OH and/or 1-3 1-3C alkoxy groups; R5 = H or 1-6C alkyl which is optionally substituted by 1-5 OH and/or 1-3 1-3C alkoxy and/or 1 or 2 phosphono groups; R6 = H or 1-6C alkyl which is optionally substituted by 1-5 OH and/or 1-3 1-3C alkoxy and/or phosphono groups and which may be interrupted by an O atom; Y = phosphono, (CONH)nR7 or NR5COR6; n = 0 or 1; R7 = 1-6C alkyl which is substituted by at least one phosphono and/or one or more COOH groups, where the phosphono group can be present as the phosphonic acid mono ester; provided that (I) contains at least one phosphono group. An Independent claim is also included for preparation of (I). |
