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

The reaction of 1 equiv of (Et 2 O)LiC 6 H 3 -2,6-Trip 2 (Trip = C 6 H 2 -2,4,6- i -Pr 3 ) with either GeCl 2 −dioxane or SnI 2 in ether affords the synthetically useful monomeric aryl−metal halides Ge(Cl){C 6 H 3 -2,6-Trip 2 } (1) and Sn(I){C 6 H 3 -2,6-Trip 2 } (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(SiMe 3 ) 2 } 2 with (Et 2 O)LiC 6 H 3 -2,6-Trip 2 results in displacement of an amide group to afford the mixed aryl/amide species Sn{N(SiMe 3 ) 2 }{C 6 H 3 -2,6-Trip 2 } (3), which also has a monomeric v-shaped geometry in the solid state.
