Octamethylcyclotetrasiloxane is cleaved quantitatively by acetyl chloride (1:1 molar ratio) in the presence of anhydrous CoCl2 in acetonitrile at room temperature to form primarily α-chloro-ω-acetoxyoligodimethylsiloxanes nOCOCH3 (n = 0-3; yield, 60-65percent)>.In the presence of an equimolar amount of trimethylacetoxysilane of hexamethyldisiloxane, the major reaction products are α-methyl-ω-acetoxyoligodimethylsiloxanes nOCOCH3 (n = 4-6; yield, 65-70percent)>.
