Synthesis

3277-26-7

2401-73-2

General procedure: The chlorination reaction needs to be carried out in THF to ensure that all Si-H bonds are chlorinated, using TCCA as the chlorinating agent (molar ratio 1:1, TCCA:siloxane). This was done as follows: 1,1,3,3-tetramethyldisiloxane and THF (ratio 20 ml THF/g siloxane) were added to the reaction flask and the mixture was cooled to -20 °C. TCCA was added in batches with vigorous stirring, and after the addition of TCCA, stirring was continued for 15 min, after which the cooling bath was removed and the reaction mixture was allowed to warm slowly to room temperature. It should be noted that the chain length of the siloxane, the type of substituent and the position of the Si-H bond may affect the method of isolation and characterization of the subsequent products. Upon completion of the reaction, THF and unreacted TCCA should be removed immediately to avoid denaturation of the products during storage.
