Building blocks for oligomeric siloxanes –selective chlorination of hydrido-siloxanes

Publication date: Available online 29 August 2018Source: Journal of Organometallic ChemistryAuthor(s): Thomas Hafner, Ana Torvisco, Frank UhligAbstractA new method was developed to achieve highly selective monochlorination of α,ω-dihydridosiloxanes, ((H)Me2SiO-(SiMe2O)n-SiMe2(H), n = 0–2; (H)R2SiO-SiR2(H); R = Me, iPr, Ph; 3,5-dihydridooctamethyltetrasiloxane, Me3SiO-(Si(H)MeO)2SiMe3) with trichloroisocyanuric acid (TCCA). The dependence of the selectivity of the monochlorination on the siloxane chain length is also discussed.Graphical abstract
