摘要: Dehydrocoupling reactions between linear poly(methylhydrosiloxane) {Me3SiO–[MeSi(H)O]n–SiMe3} and alcohols such as cholesterol, anthracene-9-carbinol, (12-crown-4)-2-carbinol, pyrene-1-carbinol, 4-methyl-5-thiazoleethanol, 4-pyridilpropanol were introduced under catalytically mild conditions. The degrees of conversion SiH bonds in polysiloxane monitored with 1H NMR spectra. reaction the 9-methoxyanthracene adduct on siloxane polymers maleimide derivatives (maleimide, N-ethylmaleimide, maleic acid anhydride) produced [2+4]-cycloadducts very high yields. © 2002 Wiley Periodicals, Inc.
