摘要：
The subject of the invention is a process for the manufacture of (iodoorganyl)alkoxysilanes of the general formula: ##STR1## in which R.sup.1 is an alkylene group, R.sup.2 is an alkoxy group and R.sup.3 and R.sup.4 an alkoxy group and/or an alkyl or aryl group, whereby the chlorine or bromine compound corresponding to that of formula (1) is caused to react with stoichiometric to double molar quantities of an inorganic iodine donor in the presence of 0.01-5 mol % of an organic substituted onium salt of nitrogen, phosphorus, arsenic or antimony or an organic substituted sulfonium salt or a crown ether as catalyst, in certain solubilizing agents.
