Title cpds. of formula (I): (where R3 is diphenylyl or the gp. (a): R4 is phenyl, diphenyl, alpha- or beta-naphthyl or the gp. (a) V1', V2' and V3' replacing V1, V2 and V3, and in which V1 and V2' are indep. sulpho gps. together with their salts, esters, amides and halides or carboxyl gps. together with their salts, esters and amides, or they are CN, Me, OH or sulphonyl; V2 and V2' are indep. H, 1-18C alkyl, 1-12C alkoxy, halogen, or sulpho gps. together with their salts, esters or amides; V3 and V3' are indep. H or 1-4C alkyl; W1 is sulpho together with the salts, esters or amides, 1-4C alkyl or alkoxy, carboxyl together with the salts, esters, or amides, CN or halogen; W1 or V1 and/or V1' may also be H; when W1 differs from H, R3 and/or R4 are diphenylyl) are prepd. by reacting 1 mol. of (II): with 1 mol. of R3-CHO and 1 mol. of R4-CHO, or 1 mol. of (II) where CHO-replaces Z3 is reacted with 1 mol. of R3-Z3 and 1 mol. of Z3-R4 (where Z3 is -CH2-PO(OR)2, -CH2(PO)ROR or -CH=P(R)3, in which R is opt. substd. alkyl, aryl or cycloalkyl) in the presence of a strongly polar solvent and an anhydrous strongly basic alkali cpd; if alkali hydroxides are used as basic alkali cpds., then they must contain =25% water. |
