Organosiloxanes with functional groups: X. Reactions of H-cyclosiloxanes with 1,4-bis(trimethylsiloxy)but-2-yne to multifunctional surface active compounds

The reaction of H-cyclosiloxanes [Me(H)SiO] n ( 1, n = 4; 2, n = 5) with 1,4-bis(trimethylsiloxy)but-2-yne ( 3) in the presence of a Pt-catalyst has been studied. Depending on the molar ratio, mono-substituted and fully substituted products were obtained in nearly quantitative yield, of which the co...

Zusammenfassung:The reaction of H-cyclosiloxanes [Me(H)SiO] n ( 1, n = 4; 2, n = 5) with 1,4-bis(trimethylsiloxy)but-2-yne ( 3) in the presence of a Pt-catalyst has been studied. Depending on the molar ratio, mono-substituted and fully substituted products were obtained in nearly quantitative yield, of which the compound 1,4-bis(trimethylsiloxy)but-2-enecyclosiloxane exists in configurational isomers.
