Effect of substituent nature on the equilibrium in the catalytic rearrangement of cyclosiloxanes in solution

  • Published:
Chemistry of Heterocyclic Compounds Aims and scope

Abstract

Determinations are made of the polymer content of mixtures obtained by catalytic rearrangement of cyclosiloxanes with various substituents (CH3, C2H5, n-C3H7, i-C4H9,C6H5, CF3CH2 CH2, NCCH2 CH2 CH2) at the silicon, in methylethyl ketone and acetone. It is found that the equilibrium cyclosiloxane-polycyclosiloxane is shifted to the left as volumes, and in particular polarities, of substituents increase. The causes of this are considered.
