Method for producing hydrocarbon oxysilicon compounds

A process for preparing silicon compound products which have hydrocarbonoxy groups and have at least one unit of the general formula (1)

• HmSi(OR)n(OR′)oR″pX4-m-n-o-p (1)
• said method comprising reacting silicon compound reactants which have at least one unit of the general formula (2)
