Description / Table of Contents:
The synthesis of C6H5me2Si—CH2—Sime2—C≡C—Sime2—CH2—Sime2C6H5 (a) is described, which forms Brme2Si—CH2—Sime2—C≡C—Sime2—CH2-Sime2Br(b) with HBr. The reaction of (b) with HBr (1-4 moles at -78°C) yields Brme2Si—CH2—Sime2Br, as well as 1,2-dibromo-ethane (main products) and Brme2Si—CH2/—Sime2CH = CHBr, Brme2Si—CH2—Sime2CH2—CHBr2.
Notes:
Es wird die Synthese des C6H5me2Si—CH2—Sime2—C≡C—Sime2—CH2—Sime2C6H52 (a) beschrieben, das mit HBr Brme2Si—CH2—Sime2—C≡C—Sime2—CH2—Sime2Br(b) bildet. Der Abbau von (b) mit HBr (1-4 Mol bei -78°C) führt zu Brme2Si—CH2—Sime2Br, sowie 1,2-Dibromäthan (Hauptprodukte) und Brme2Si—CH2—Sime2—CH≡CHBr, Brme2Si—CH2—Sime2—CH2—CHBr2.
