Synthesis of organocyclosiloxanes with polar substituents in the organic group

Article abstract of DOI:10.1007/BF01179695

1. Six organocyclotetrasiloxanes were synthesized, and of these the following four are new: 3-acet-oxypropyl)heptamethylcyclotetrasiloxane, [5-acetoxy-2-(acetoxymethyl)pentyI]heptamethylcyclotetrasiloxane, heptamethyl[5,5,5-trifluoro-2-(trifluoromethyl)pentyl]cyclotetrasiloxane, and hexamethylbis[5,5,5-trifluoro-2-(trifluoromethyl)pentyl]cyclotetrasiloxane. 2. The replacement of one methyl group in octamethylcyclotetrasiloxane by a 3,3,3-trifluoropropyl group leads to a great increase in the rate of polymerization.
