Introduction (引论) Historical Development and Current Trends in Organometallic Chemistry (在金属有机化学领域的历史发展和当前趋势) ? 1760 The cradle( 摇篮) anometallic chemistry is a Paris military pharmacy( 制药厂). It is there Cadet( 军校学员) works on sympathetic inks (隐显墨水) based on cobalt salts. For their preparation, cobalt mineral which contain arsenic( ***) was used. ? As 2O 3 + 4CH 3 COOK ?“ Cadet ’ s Fuming liquid ”(军学生发烟液体) ? Contains cacodyloxide (卡可基氧化物) [(CH 3) 2 As] 2O ? Malodorous (恶臭的) ? pound ( 首个有机金属化合物).? 1827 Zeise ’ s salt (蔡斯盐) Na[PtCl 3C 2H 4] ? First plex (首个烯烃配合物) . ? 1840 R. W. Bunsen (本生) continues the study of pounds which he names “ alkarsines ”(卡可基酸氧化物) . The weakness of As-As bond in molecules of the type R 2 As-AsR 2 led to a profusion ( 丰富) of derivatives ( 衍生物) like (CH 3) 2 whose taste is checked by Bunsen ! ? 1849 E. Frankland (弗兰克兰) , student of Bunsen, attepts the preparation of an “ ethyl radical ”(乙基自由基). (cacodyl as well was taken to be a radical). ? 1852 Frankland prepares the important pounds ( 烷基***化合物) : ? 2CH 3 X + 2Na/Hg ? (CH 3) 2 Hg + 2NaX ? Additionally: (C 2H 5) 4 Sn, (CH 3) 3 B (1860). ? In the following years, alkyl transfer reactions (烷基转移反应) using R 2 Hg and R 2 Zn serve in the synthesis of numerous main-group organometallics (众多的主族金属有机化合物的合成) . ? Frankland also introduced the concept of valency (化合价概念) “ combining power ” and the term organometallic (有机金属主干). ? 1852 K. J. Konig (康尼) and M. E. Schweizer in Zurich (苏黎世) first prepare (C 2H 5) 4 Pb from ethyliodide (乙基碘) and Na/Pb alloy (合金) . In a similar manner, they also obtain (C 2H 5) 4 Sb and (C 2H 5) 3 Bi. ? 1859 W. Hallwachs and A. Schafarik generate alkylaluminum (烷基铝) iodides: ? 2Al + 3RI ? R 2 AlI + RAlI 2 ? 1863 C. Friedel (弗瑞德) and J. M. Crafts (克莱福特) anochlorosilane (有机***硅烷) :? SiCl 4 + m/2ZnR 2? RmSiCl 4-
