(1,1,3,3-Tetramethylallyl)lithium (1), prepared by cleaving the corresponding phenyl sulfide at -92 o C with lithium 1-(dimethylamino)naphthalenide or by reacting of trimethyltin derivative with CH 3 Li in THF/diethyl ether/TMEDA at -78 o C, adds rapidly to naphthalene and 1-(dimethylamino)naphthalene at -78 o C to give mixtures of the corresponding 1-substituted 1,2- and 1,4-dihydronaphthalenes
(1,1,3,3-四甲基烯丙基)锂 (1),通过在 -92 o C 下用 1-(二甲氨基)萘基锂裂解相应的苯基硫化物或通过三甲基锡衍生物与 CH 3 Li 在 THF/二乙基酯中反应制备乙醚/TMEDA 在 -78 o C 下,在 -78 o C 下快速加入萘和 1-(二甲氨基)萘中,得到相应的 1-取代的 1,2- 和 1,4-二氢萘的混合物
