Abstract:
A water-soluble furylphosphine corresponding to the general formula (I): in which:a represents an integer from 1 to 3, at least one R2 radical represents a hydrophilic group comprising: â€”SO2M, â€”SO3M, â€”CO2M or â€”PO3M, M representing an inorganic or organic cationic residue comprising a proton, cations derived from alkali metals or alkaline earth metals, ammonium cations â€”N(R)4 in the formula of which the R symbols, which are identical or different, represent a hydrogen atom or an alkyl radical having from 1 to 12 carbon atoms or the other cations derived from metals the salts of furylsulphinic acid, of furylcarboxylic acid, of furylsulphonic acid or of furylphosphonic acids of which are water-soluble. N(R)3X, in which formula the symbols R, which are identical or different, represent a hydrogen atom or an alkyl radical containing from 1 to 12 carbon atoms, X represents an organic or inorganic anion, â€”OH, R1 represents a hydrophilic group according to the definition given for R2 or an alkyl or alkoxy group containing 1 to 12 carbon atoms; a halogen atom, a nitrile group or a haloalkyl group containing 1 to 12 carbon atoms, m represents 1 or 2, p represents an integer from 0 to 3, when m is equal to 2, an R2 radical can also represent an alkyl or alkoxy group containing 1 to 12 carbon atoms, a nitrile group or a haloalkyl group containing 1 to 12 carbon atoms.
