Abstract:
The reaction of dichloro(methyl)silane, dichloro(phenyl)silane or dichloro(dimethyl)silane with one equivalent of the lithiated aryl pincer ligands [2,6‐(DoCH 2 ) 2 H 3 C 6 ]Li leads to the chlorosilanes [2,6‐(DoCH 2 ) 2 H 3 C 6 ]SiRR′Cl 1 – 6 , respectively, as thermolabile oily compounds. Treatment of 1 – 6 with trimethylsilyl triflate leads to the crystalline ionic silicon triflates [2,6‐(DoCH 2 ) 2 H 3 C 6 SiRR′] + · X – 7 – 12 , respectively [(X = OSO 2 CF 3 ), 1 , 7 : Do = OMe, 2 , 8 : Do = SMe, 1 , 2 , 7 , 8 : R = Me, R′ = H; 3 , 9 : Do = OMe, 4 , 10 : Do = SMe, 3 , 4 , 9 , 10 : R = Ph, R′ = H; 5 , 11 : Do = OMe, 6 , 12 = SMe, 5 , 6 , 11 , 12 : R, R′ = Me]. The compounds 1 – 12 are characterized by NMR spectroscopy, by conductivity measurements, and by X‐ray crystallography ( 8 – 12 ). The NMR parameters δ Si, 1 J (SiH) and δ H(SiH) and some structural data are compared with those of known compounds containing one NCN‐pincer aryl ligand or two aryl substituents of the type [2‐(DoCH 2 ) 2 H 4 C 6 ]. Differences in bonding depending on the type of the donor Do (NMe 2 , OMe, SMe) are discussed.
