“…The monomeric structure of trimethylaluminium in THF could lead to a higher reactivity of this compound in these applications. Different THF adducts of trimethylaluminium are known (Kong et al, 1995;Vidyaratne et al, 2009;Tanner et al, 1993), but on the one hand the trimethylaluminium-THF adduct is obtained as a co-crystallate and on the other it is part of a calcium sandwhich complex. Many ether adducts of AlMe 3 are also known (see e.g.…”

“…The reaction of decamethylcalcocene with trialkylalane in THF gave the loose adduct 3 , 11 whereas the use of calcium bis[bis(trimethylsilyl)amide] led to the elimination of dialkylaluminum amide and to the formation of dimeric bis(trimethylsilyl)amidocalcium tetrakis(trimethylsilylmethyl)alanate ( 4 ) 12. The alanate anions bind as bidentate ligands with Ca−C bond lengths of 263.8 and 267.8 pm.…”

“…Die Umsetzung von Decamethylcalcocen mit Trialkylalan lieferte in THF das lockere Addukt 3 , 11 während die Verwendung von Calciumbis[bis(trimethylsilyl)amid] zur Eliminierung von Dialkylaluminiumamid und zur Bildung des dimeren Bis(trimethylsilyl)amidocalciumtetrakis(trimethylsilylmethyl)alanats 4 führt,12 bei dem die Alanationen als zweizähnige Liganden mit Ca‐C‐Bindungslängen von 263.8 und 267.8 pm auftreten. Die Eliminierung eines weiteren Moleküls (Me 3 Si) 2 NAl(CH 2 SiMe 3 ) 2 aus 4 unter Bildung von Dialkylcalcium misslang bisher jedoch.…”
