Intramolecularly coordinated diarylindium and diarylthallium chlorides [(8-Me2NC10H6)2E]Cl (E=In, Tl) with essentially ionic structures

Abstract

The reaction of 8-Me 2 NC 10 H 6 Li · Et 2 O with InCl 3 and TlCl, respectively, followed by work-up under aerobic conditions, provided the intramolecularly coordinated diarylelement chlorides [(8-Me 2 NC 10 H 6 ) 2 E]Cl ( 1 , E = In; 2 , E = Tl) in reasonable yields. Single crystal X-ray structure analyses of 1 and 2 revealed that both compounds essentially contain centrosymmetric dimers of [(8-Me 2 NC 10 H 6 ) 2 E] + cations (E = In, Tl) that are loosely associated by the chloride ions.

Peri‐Interactions in 8‐Diphenylphosphino‐1‐bromonaphthalene, 6‐Diphenylphosphino‐5‐bromoacenaphthene, and Derivatives

“…[1][2][3] Much of the earlier work on peri-substituted naphthalenes revolved around 1,8-dimethylaminonapththalene, (1,8-Me 2 N) 2 -Nap, (A), which has found applications as a proton sponge (Scheme 1). [ The facile C-H lithiation of dimethylnaphthylamine Me 2 N-Nap (B) using n-butyllithium [5] and subsequent salt metathesis with (organo)element halides proved to be a straight-forward route for the synthesis of intramolecularly coordinating 8-dimethylaminonaphthylelement species 1-(R n E)-8-(Me 2 N)-Nap (C) featuring the elements E = B, [6,7] Al, [8][9][10][11][12] Ga, [10] In, [10,13] Tl, [13] Si, [14][15][16][17][18][19][20] Sn, [14,[21][22][23][24]] P, [25][26][27][28] As, [30,31] Sb, [31,32] Bi, [31,33] S, [34][35][36][37][38] Se, [39][40]…”

Lewis pairing and frustration of group 13/15 elements geometrically enforced by (ace)naphthalene, biphenylene and (thio)xanthene backbones

“…Besides boron and aluminium, a few Ga, In and Tl derivatives featuring 8-dimethylamino-naphthyl substituents were reported. 31,34 The dichlorogalane 26 was obtained as a monomer, while the corresponding indium derivative 27 formed a dimer with bridging Cl ligands (Chart 6). Both compounds were structurally characterised.…”

“…In 2012, Beckmann et al reported dinaphthyl substituted In and Tl derivatives 28 and 29 (Chart 6). 34 The two compounds adopt similar dimeric structures in the solid state with bridging Cl ligands. Both In and Tl are six-coordinate and sit in distorted octahedral geometries, with the two naphthyl substituents occupying trans positions (C-E 13 -C bond angles = 158.1(1)° for In and 171.1(3)° for Tl).…”

Peptidyl Succinimidyl Peptides as Taspase 1 Inhibitors

“…The facile C–H lithiation of dimethylnaphthylamine Me 2 N–Nap ( B ) using n ‐butyllithium5 and subsequent salt metathesis with (organo)element halides proved to be a straight‐forward route for the synthesis of intramolecularly coordinating 8‐dimethylaminonaphthyl‐element species 1‐( R n E )‐8‐(Me 2 N)‐Nap ( C ) featuring the elements E = B,6,7 Al,8–12 Ga,10 In,10,13 Tl,13 Si,14–20 Sn,14,21–24 P,25–28 As,30,31 Sb,31,32 Bi,31,33 S,34–38 Se,39–41 and Te 30–48. Within these compounds, short E ··· N transannular distances are frequently observed, which are indicative of strong attractive interactions.…”
