Abstract

The crystalline dilithium diamides [Li2 (μ-A)] 21,[Li (μ-A){μ-Li (thf)(μ-thf)}] 22,[Li (thf) 2 (μ-A) Li (thf)] 3,[{Li (tmen)} 2 (μ-A)] 4,[{Li (μ-A′)(thf) 2}(μ-Li)] 25,[{Li (tmen)} 2 (μ-A ″)] 6,[{Li (μ- B′)(thf)}(μ-Li)] 27,[{Li (tmen)} 2 {μ-NSi (Me) 2C10H6N-1, 8}] 9 and [{Li (tmen)} 2 (μ-B)] 13 and aminolithium amides [Li {(μ-NC10H6NH-1, 8) SiMe2}(OEt2)] 28,[Li (tmen) 2 {NSi (Me) 2C10H6NH-1, 8}] 12 and [Li (tmen){μ-NSi (Me) 2C10H6NH-1, 8}] 15 have been prepared ...
