Synthesis and Characterization of the Monomeric Terphenyl−Metal Halides Ge(Cl){C₆H₃-2,6-Trip₂} (Trip = C₆H₂-2,4,6-<i>i</i>-Pr₃) and Sn(I){C₆H₃-2,6-Trip₂} and the Terphenyl−Metal Amide Sn{N(SiMe₃)₂}{C₆H₃-2,6-Trip₂}

Abstract

The reaction of 1 equiv of (Et2O)LiC6H3-2,6-Trip2 (Trip = C6H2-2,4,6-i-Pr3) with either GeCl2−dioxane or SnI2 in ether affords the synthetically useful monomeric aryl−metal halides Ge(Cl){C6H3-2,6-Trip2} (1) and Sn(I){C6H3-2,6-Trip2} (2). The compounds have monomeric structures with two-coordination and v-shaped geometries at the group 14 element in the solid state. Treatment of the amide Sn{N(SiMe3)2}2 with (Et2O)LiC6H3-2,6-Trip2 results in displacement of an amide group to afford the mixed aryl/amide species Sn{N(SiMe3)2}{C6H3-2,6-Trip2} (3), which also has a monomeric v-shaped geometry in the solid state.
