Balancing Donor‐Acceptor and Dispersion Effects in Heavy Main Group Element π Interactions: Effect of Substituents on the Pnictogen⋅⋅⋅π Arene Interaction

“…[9] In addition to numerous examples showing intermolecular pnicogen···π arene interaction, systems with intramolecular interaction were less frequently reported, especially for bismuth. [10][11][12][13][14][15][16][17][18] However, these instances demonstrate that this rather weak interaction enables stabilization of unusual compounds and might support catalytic processes. [14] In order to rationalize what determines molecular and crystal structures, understanding the basic components of the pnictogen···π arene interaction is essential.…”

“…Furthermore, such weak interactions might also play a crucial role in some biological systems as discussed by Frontera and coworkers . In addition to numerous examples showing intermolecular pnicogen⋅⋅⋅π arene interaction, systems with intramolecular interaction were less frequently reported, especially for bismuth . However, these instances demonstrate that this rather weak interaction enables stabilization of unusual compounds and might support catalytic processes …”

2,6‐Diisopropylphenyl‐Substituted Bismuth Compounds: Synthesis, Structure, and Reactivity

“…Moreover, diaryl bismuth halides of the heavier halogens can be prepared via halogen exchange reactions with alkaline or earth alkaline metal halides and diaryl bismuth halides of lighter halogens [1,11,12] . It is common for bismuth halides to show secondary bonding interactions between bismuth and halogen atoms of neighboring molecules in the solid state [8–10,12–14] . The tendency for intermolecular interactions lowers when sterically more demanding substituents are employed [2,4] .…”

Syntheses, solid-state structures, solution behavior of hypervalent organobismuth(III) compounds [2-(Et2NCH2)C6H4] BiX3− and DFT characterization of [2-(Me2NCH2)C6H4] BiX3− [X = Cl, Br, I; n= 1–3]

“…Recent developments show that these difficulties can be overcome at least partially by two strategies. One is the use of bulky substituents such as (Me 3 Si) 2 CH [9][10][11][12][13][14], 2,6-R 2 C 6 H 3 (R = Mes [15][16][17][18][19], 2,6-i Pr 2 C 6 H 3 [18]), 2,4,6-R 3 C 6 H 2 [(Me 3 Si) 2 CH [20][21], Ph [22,23]], 2,6-[(Me 3 Si) 2 CH] 2 -4-(Me 3 Si) 3 C-C 6 H 2 [24][25][26][27], 2,6-Mes 2 -4-t Bu-C 6 H 2 [19]. Another strategy is to use one pendant arm ligands such as 2-(MeOCR 2 )C 6 H 4 (R = Me [28][29][30], CF 3 [31]) and 2-(Me 2 NCH 2 )C 6 H 4 [32], or ''pincer" ligands like 2,6-(Me 2 NCH 2 ) 2 C 6 H 3 [32,33], 2,6-[MeN(CH 2 CH 2 ) 2 NCH 2 ] 2 C 6 H 3 [33], and 2,6-(ROCH 2 ) 2 C 6 H 3 (R = Me [34], t Bu [34,35]).…”
