The transamination of 8-(tert-butyldimethylsilylamino)quinoline with (thf) 2 Cr[N(SiMe 3 ) 2 ] 2 yields monomeric bis[8-(tert-butyldimethylsilylamido)quinoline]chromium(II) (1). Similar reactions of M[N(SiMe 3 ) 2 ] 2 (M = Mn, Fe, Co) with 8-(trialkyl-silylamino)quinoline lead to the formation of monomeric bis[8-(trialkylsilylamido)quinoline]metal(II) [M = Mn, SiR 3 = SiMe 2 tBu (2a), SiiPr 3 (2b);
8-(叔丁基二甲基甲硅烷基氨基)喹啉与(thf) 2 Cr[N(SiMe 3 ) 2 ] 2 的氨基转移产生单体双[8-(叔丁基二甲基甲硅烷基氨基)喹啉]铬(II) (1)。M[N(SiMe 3 ) 2 ] 2 (M = Mn, Fe, Co) 与 8-(三烷基-甲硅烷基氨基)喹啉的类似反应导致形成单体双[8-(三烷基甲硅烷基氨基)喹啉]金属(II) [M = Mn,SiR 3 = SiMe 2 tBu (2a),SiiPr 3 (2b);M = Fe、SiR 3 = SiMe 2 tBu (3a)、SiiPr 3 (3b);M = Co、SiR 3 = SiMe 2 tBu (4a)、SiiPr 3 (4b)]。8-氨基喹啉与 M[N(SiMe 3 ) 2 ] 2 (M = Mn, Fe, Co) 的转氨基作用可以分离杂配 1:1 和均配 2:1 产物。1:1 配合物双 [8-氨基喹啉金属
