PURPOSE: New phosphanes are provided, which are appropriate to the use of catalyst for organic synthesis. CONSTITUTION: A compound is disclosed having the formula(I), in which m equals 1 to1000; x equals 0 to 4; W is a group of formulas -CH2-CH2-, -CH(CH3)CH2- or -CH2CH(CH3)-; R is hydrogen, a straight-chain or branched-chain C1-C5 alkyl radical; or a group of formulas (a) or (b), in which a, b, c, d and e independently represent a number from 0 to 1000, at least one of the numbers represented by a, b, c, d and e being higher than 0; R(5), R(6), R(7), R(8) and R(9) are the same or different and represent hydrogen, C1-C5 alkyl or a group of formula (c); R(1) and R(2) are the same or different and represent a straight-chain, a branched-chain or a cyclic C1-C30 alkyl radical or C6-C10 aryl radical which is non-substituted or substituted by one to five C1-C3 alkyl radicals, or R(1) and R(2) form together with the trivalent P atom a dibenzophospholyl of formula (d) or a 3,4-dimethylphospholyl of formula (e); and L stands for C1-C5 alkyl, C1-C5 alkoxy, NO2, NR(3)R(4), R(3) and R(4) independently representing hydrogen or C1-C4 alkyl, or for Cl or OH |
