Attempted reduction of a carbazolyl-diiodoalane

Abstract

A carbazolyl-diiodoalane was prepared and subjected to reducing conditions with KC8, Mg(i) compounds, or Cp*2Co.

Modulating the Frontier Orbitals of an Aluminylene for Facile Dearomatization of Inert Arenes**

“…afforded the first stable iminoalane with an Al�N triple bond. [14] Shortly thereafter, we [15] and Hinz [16] independently reported an isolable N-aluminylene 1. The coordination chemistry of the tri-active ambiphilic 1 with transition metals has been documented.…”

“…D reveals high reactivity for facile cleavage of hydrogen, [13] while the reaction of D with ArN 3 (Ar=C 6 H 3 ‐2,6‐(C 6 H 2 ‐2,4,6‐Me 3 ) 2 ) afforded the first stable iminoalane with an Al≡N triple bond [14] . Shortly thereafter, we [15] and Hinz [16] independently reported an isolable N‐aluminylene 1 . The coordination chemistry of the tri‐active ambiphilic 1 with transition metals has been documented [15] .…”

Precise Transfer of an Aluminium Atom: An Avenue to Aluminium Heterocycles

“…[23] Despite such utility, synthetic routes towards alumoles are exceedingly limited and largely rely on the employment of organo-dilithium [24] or zirconocene-based [21,25] reagents. There is only a single report describing alumole syntheses via carboboration of the aluminum dialkynyl LAl(CCR)2 (L = N, N-chelate ligand and R = organic group) with B(C6F5)3 by Roesky, Zhu, Wang et al [23] Recently, following the first isolation of a stable free aluminylene (alanediyl) :AlAr iPr8 (Ar iPr8 = C6H-2,6-(C6H2-2,4,6i Pr3)2-3,5-i Pr2) by Power, Tuononen et al, [26] we [27] and Hinz [28] group independently demonstrated an isolable free carbazoly aluminylene 1 (Figure 2). The reactivity of :AlAr iPr8 with hydrogen [26] and organic azides [29] as well as the coordination chemistry of 1 with transition metals [27] and Lewis bases [30] were further explored.…”

Functionalized Carbazolyl Hydro‐ and Allyl‐Silanes

“…[20] By employing the 1,8-bis(3,5-di-tertbutyl-phenyl)-3,6-di-tert-butyl-carbazolyl system (R), our group recently reported on the generation of formally one-coordinate tetrylenylium cations [RE] + (E = Si, Ge, Sn, Pb) [21,22] and the attempted reduction of a carbazolyl-diiodoalane. [23] Featuring this carbazole scaffold R, we now describe the synthesis and properties of two series of compounds, RSi(X) 2 H and RSi(X) 2 All (X=Cl, N 3 , NCO, NCS, NH 2 , All=CH 2 CHCH 2 ).…”

“…Examples include 1,8‐diphenyl‐3,6‐dimethyl‐carbazolyl‐dimethylalane, [18] 1,8‐dimesityl‐3,6‐di‐tert‐butyl‐carbazolyl‐magnesiumiodide [19] and 1,8‐dimesityl‐3,6‐dimethyl‐carbazolyl‐dichlorogallane [20] . By employing the 1,8‐bis(3,5‐di‐tert‐butyl‐phenyl)‐3,6‐di‐tert‐butyl‐carbazolyl system (R), our group recently reported on the generation of formally one‐coordinate tetrylenylium cations [RE] + (E=Si, Ge, Sn, Pb) [21,22] and the attempted reduction of a carbazolyl‐diiodoalane [23] .
