Abstract (en)
[origin: FR2857663A1] 4-(Tert. butyl)-4'-methoxydibenzoyl methane derivatives (I) are new. Dibenzoylmethane derivatives of formula (I) and their salts and solvates are new. [Image] R 1-R 4, R' 1-R' 4H, 1-4C alkyl, 2-4C alkenyl, 2-4C alkynyl, 1-4C alkoxy, halo, OH, NH 2, NO 2, amido or -CO-T; Y : OH, OR or SR; R : 1-4C alkyl; and R 5, R' 5H, 1-4C alkyl, 2-4C alkenyl, 2-4C alkynyl, 5-20C linear or branched, saturated or unsaturated, acylic carbon chain (optionally terminally functionalized and/or interrupted by N (in an amide or amine function) and/or O (in an ether or carboxy function). An independent claim is included for the preparation of (I). N.B. In the disclosure the parent compound 4-(tert. butyl)-4'-methoxydibenzoyl methane, i.e. the keto form of (I; R 1- R 5, R' 1- R' 5= H) or Parsol 1789(RTM), is stated to be known; and the claimed preparation of (I) implies that R 5and/or R' 5must be other than H.
