Abstract

The invention concerns bi-aromatic compounds of formula (I) in which Ar represents (a), Z being O or S, R1 is CH3, —CH2—O—R6, —OR6 or —COR7; R2 is —OR8, —SR8 or a polyether radical if in the latter case R4 is C1-C20alkyl and is in ortho or meta position relative to X—Ar; R3 is alkyl or R2 and R3 together form a cycle optionally interrupted by O or S; R4 is aryl radical; R5 is H, halogen, C1-C20 alkyl or —OR8; R6 is H, alkyl or —COR9; R7 is H, alkyl, —N(r′)(r″) or —OR10; R8 is H, alkyl or —COR9; R9 is alkyl; R10 is H, C1-C20 alkyl, alkenyl, monohydroxyalkyl or polyhydroxyalkyl, aryl or aralkyl or a sugar residue, r′ and r″ are H, alkyl mono- or polyhydroxyalkyl, aryl, an amino acid or sugar residue or together form a heterocycle, X represents a radical of formula (d) or (e) in which R11 is H or —OR6; R12 is H or alkyl; or R11 and R12 form an oxo radical, and the salts, optical and geometrical isomers of the compounds of formula (I).
