In, Tl) and NaR\* via isolable R\* 2 ECl (reaction of GaCl 3 and NaR\* leads to R\* 2 GaէGaR\* instead of R\* 2 Ga-GaR\* 2 ), (ii) from EBr (E = In, Tl) and NaR\* or NaRЈ (reaction of AlBr or GaBr and NaR\* leads to R\* 4 Al 4 or R\* 8 Ga 18 and R\* 8 Ga 22 ), (iii) from NaGa 2 R\* 3 and Me 3 SiCl.
The reaction of InBr 3 with LiR\* ´(THF) n (R\* = ±C(SiMe 3 ) 3 , THF = OC 4 H 8 ) in a 1 : 1 molar ratio forms [Li(THF) 4 ][R\*InBr 3 ] in good yield. The properties and some spectroscopic data ( 1 H, 13 C, 29 Si, 7 Li±NMR, IR and Raman) of this trisyl-tribromoindate are given and the crystal struc
