Reaction Conditions:

with hydrogenchloride in diethylene glycol dimethyl ether at 60; for 1.33 h;

Steps:

2c Examples 1a- U
General procedure: The organosilanes indicated in Table 4 as starting compounds were reacted with the HCI/diethyl ether reagent (molarity of HCI in diethyl ether: 5 molIl). The reactions were performed by mixing the reaction partners, i.e. the respective organosilane (0.1 ml) and the HCI/diethyl ether solution (0.4 ml) in an NMR tube. After cooling the sample with liquid nitrogen (-196 °C), the tube was evacuated under vacuum (-0.1 mbar), and sealed. NMRspectra were recorded depending on reaction time and temperature. The molar ratios of products formed were determined by integration of relevant NMR signals that were assigned to specific products within the mixture. After optimization and completion of the chlorination reaction SiH + HCI - SiCI + H2 the NMR tube was opened to analyze the product mixture by GC-MS. Product identification was verified in all cases for the main products.Table 4 shows the results obtained in the synthesis of organochlorosilanes from organohydridosilanes with the HCI/Et20 reagent in Examples Ia to lu:_The reactions were performed as described for example 1, except that a HCI/diglyme chlorination reagent (molarity of HCI in diglyme: 10 mol/l) was used instead of HCI/diethyl ether reagent.Table 5 shows the results obtained in the synthesis of organochlorosilanes from organohydridosilanes with the HCI/diglyme chlorination reagent in Examples 2a to 2s.
