An intramolecularly base-stabilized monomeric organoaluminum dihydride

Aluminum alkyls with intramolecularly coordinated oxygen

“…We have also used 2 as a precursor for the preparation of other organoaluminum derivatives with O,C,O-chelating ligands (4)(5)(6).…”

Synthesis and protonolysis of neutral aluminum dihydride compounds stabilized by tridentate-substituted pyrrolyl ligands: Synthesis, structural characterization and ring-opening polymerization of ɛ-caprolactone

“…Treatment of 2 with one or two equivalents of 2,6-diisopropylainiline or triphenylsilanol in a methylene chloride solution at room temperature led to the rapid evolution of hydrogen, and the compounds [C 4 H 2 N{2,5-(CH 2 NMe 2 ) 2 (10) were isolated in good yield. Compounds 7,8,9, and 10 were also characterized by 1 H and 13 C NMR spectroscopy, which showed similar resonance patterns as those described for the previous compounds.…”

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

“…Amongst these, the most frequently studied are indium compounds that contain the substituents A (Khan et al , 1980 ;Jastrzebski et al , 1982 ;Steevensz et al , 1985 ;Schumann et al , 1990Schumann et al , , 1992Schumann et al , , 1994Cowley et al , 1995 ;K ü mmel et al, 1996 ;Olazabal et al , 1996 ;Hair et al , 2000 ;Schachner et al , 2006Schachner et al , , 2008 and B (Schumann et al , 1989(Schumann et al , , 1991Cowley et al , 1994Cowley et al , , 1995Olazabal et al , 1994 ;Contreras et al , 1995 ;K ü mmel et al, 1996 ;Dam et al , 1997 ;Lomeli et al , 1998 ), but there is only one example comprising the substituent C , namely, the arylindium dichloride 8-Me 2 NC 10 H 6 InCl 2 (Hair et al , 2000 ). Furthermore, there are only two publications dealing with thallium compounds containing the substituents A ( Van der Ploeg et al , 1981 ;Vicente et al , 1989 ) and B (Van der Ploeg et al , 1981 ) whereas thallium compounds carrying the substituent C have not yet been described.…”
