摘要：

Tetrakis[bis(trimethylsilyl)methyl]dialane(4) (1) with-an Al-Al bond reacts with sodium or potassium in 1,2-dimethoxyethane to yield dark blue radical monoanions [R2Al-AlR2].-, which are quite persistent after recrystallization and can be characterized speCtroSCopically (ESR, UV-VIS, IR) as pi-radicals. Surprisingly, similar compounds are formed by the single electron transfer reaction of 1 with neopentyl- or trimethylsilylmethyl-lithium in the presence of the chelating N,N,N',N'-tetramethylethylenediamine. diamine.
