Solution NMR and FT-IR studies on the reactions and the complexes of silyl ethers with triethylaluminium

摘要: Complexation and reactions of silyl ethers RnSi(OMe)4−n (n = 0−3, R Ph, alkyl) with AlEt3 were studied in benzene followed by 13C 29Si NMR. In the presence excess AlEt3, five consecutive steps: alternating complexation alkylation ethers, Ph(Et)nSi(OMe)3−n 1.2), dialkyl-aluminium alkoxodes, (Et2AlOMe3)n 2.3).
