Yield:1719-58-0 238 g

Reaction Conditions:

Stage #1:tetramethyldivinyldisiloxane with aluminum (III) chloride in n-heptane at 70; for 5 h;Inert atmosphere;
Stage #2: with acetic anhydride in n-heptane at 70 - 75; for 4 h;

Steps:

1.1; 1; 2-4 (1) Synthesis of ViMe2SiCl:
Add 186g ViMe2SiOSiMe2Vi, 186g n-heptane, 130g anhydrous aluminum chloride to a four-necked flask with nitrogen, mechanical stirring and dropping funnel. At 70,After 5 hours, a mixed solution containing 186g of acetic anhydride and 186g of n-heptane was added dropwise, and the temperature was maintained at 7075 during the dropping process.After the addition is complete, reflux for 4 hours, and then obtain 238 g of ViMe2SiCl with a GC purity of 99.61% through rectification.
