The synthesis and characterization of the primary terphenyl silanes and chlorosilanes 2,6-Mes2C6H3SiCl3 (1a), 2,6-Trip2C6H3SiCl3 (1b), 2,6-Mes2C6H3SiHCl2 (2a), 2,6-Trip2C6H3SiHCl2(2b) 2,6-Mes2C6H3SiH3(3a), 2,6-Trip2C6H3SiH3 (3b) and 2,6-Mes2C6H3SiCl2SiCl3(4), (where Mes = 2,4,6-Me3C6H2 and Trip = 2,4,6-i-Pr3C6H2) are described. Compounds (1a, 1b), (2a, 2b) and (4) were prepared by the reaction between SiCl4, SiHCl3 or Si2Cl6, respectively, and the appropriate aryl lithium reagent (2,6-Mes2C6H3Li or 2,6-Trip2C6H3Li·OEt2). Compounds (3a) and (3b) were prepared by reduction of (1a) and (1b) with LiAlH4, respectively. The derivatives (1a) - (3a) were characterized by 1H, 13C, 29Si NMR and IR spectroscopy. The structures of (1a), (1b) and (4) have been determined. Crystal data with CuKα (λ = 1.54178 A) at 130 K: (1a), a = 9.074(2) A, b = 16.681(3) A, c = 15.842(3) A, β = 105.20(3)°, V = 2313.9(8) A3, Z = 4, space group P21/c, 2772 (I > 2σ(I)) data, R = 0.042; (1b), a = 12.197(2) A, b = 25.602(5) A, c = 11.098(...
