A process and use of at least one catalyst for phosphorylation, in particular phosphitylation, of hydroxyl groups, whereby a phosphorous compound is added to a hydroxyfunctional compound having at least one hydroxyl group. The addition yields a phosphorylated product having at least one O-P bond. The catalyst employed in the process is of the general formula (R1)nX(R2)4-n, wherein each R1 independently is hydrogen, at least one hydrocarbyl, amino, halogenated and/or silylated hydrocarbyl group, X is Si, Ge or Sn, each R2 independently is a leavening group and is F, Cl, Br, I or a sulphonate group optionally being halogen substituted and wherein n is 1, 2 or 3. |
