Abstract
Ligands for the formation of ambiphilic catalysts and method for obtaining them These comprise a hydrophobic part, a hydrophilic part and a donor or phosphine group having the general formula I < IMAGE > in which: R1 may be an < IMAGE > chain CxH2x+1 or a -CxH2x+1 with a value of x between 5 and 20, R2 and R3 may be an alkyl or aryl group, n has a value between 1 and 99, and m has a value between 1 and 5. The method, which comprises a first stage of synthesis of the chlorinated products and a second stage of synthesis of phosphines, is characterized in that the starting material is an easily accessible non-ionic surfactant.
