Hexamethyl-1,2,3-tristanna-[3]ferrocenophane (1) was prepared by the reaction of 1,1′-bis(dimethylstannyl)ferrocene (3) with bis(diethylamino)dimethylstannane. The molecular structure of 1 was determined by X-ray crystallography. The monoclinic unit cell (space group P21/c; a = 18.659(4), b = 17.311(3), c = 13.719(3) A; β = 111.02(3)°) contains two independent molecules which differ slightly in their
六甲基-1,2,3-三锡烷-[3]二茂铁 (1) 是通过 1,1'-双(二甲基锡烷基)二茂铁 (3) 与双(二乙氨基)二甲基锡烷反应制备的。1的分子结构由X射线晶体学确定。单斜晶胞(空间群 P21/c;a = 18.659(4), b = 17.311(3), c = 13.719(3) A;β = 111.02(3)°)包含两个独立的分子,它们的分子结构略有不同构象。环戊二烯基环几乎平行,但取代碳原子的位置相对于黄道位置扭曲了 τ 62°。研究了 1 对碘和硫属元素 E (E = S, Se, Te) 的反应性。碘反应生成 1,1'-双[碘(二甲基)锡烷基]二茂铁 (6) 和二碘化二甲基锡。对于硫属元素,可检测和分离的产物为 1,3-distanna-2-硫属元素-[3]二茂铁(E = S (7)、Se (8)、Te (9))以及三聚二甲基锡硫属元素化物 (Me2SnE)3。可以从 1,
