Phosphine compounds of formula (I) are new. m = 1-1000;x = 0-4; W = -CH2CH2-, -CHMeCH2- or -CH2CHMe-; R = H, 1-5C alkyl or a group of formula (A) or (B); a-e = 0-1000; at least one of the numbers a-e is more than 0; R<5>-R<9> = H, 1-5C alkyl or a group of formula (C); R<1>, R<2> = linear, branched or cyclic 1-30 alkyl or 6-10C aryl (optionally substituted with 1-5 1-3C alkyl groups), or R<1> + R<2> + P = a dibenzo-phosphoryl or 3,4-dimethyl-phosphoryl group of formula (D) or (E); L = 1-5C alkyl or alkoxy, NO2 or NR<3>R<4> (with R<3>, R<4> = H, 1-4C alkyl, Cl or OH). Also claimed is a process for the production of (I) from the corresponding phenol, by deprotonation with base followed by reaction with a compound of formula X-(W-O)m-R, in which X is a nucleophilically substitutable leaving group. |
