| 内容記述 | Organic compounds containing carbon-metal bonds are called organometallic compounds. Such compounds have been known and studied since the 19 century and have been widely used for synthetic transformation in modern organic chemistry. Their many educational benefits could result in the use of reaction types and discoveries in undergraduate and graduate classes in organic and organometallic chemistry. The repeating growth reaction of alkylaluminum with ethylene was discovered by Ziegler. An anomalous result was obtained on one occasion. Instead of converting ethylene into a mixture of ethylene oligomer, its dimer, i.e., 1-butene, was almost the only product. The promoter for this unexpected reaction was eventually found to be a trace of nickel salts, which was accidentally mixed into the reaction due to the use of an uncleaned metal autoclave after a hydrogenation experiment (Nickel effect). Since nickel salt could have such a marked influence on the course of ethylene with alkylaluminium, curiosity was aroused about the influence of transition metal salts. Ziegler and his group finally found that salt of Ti markedly accelerated the growth reaction, leading to the deposition of polyethylene. Natta found sterically controlled polypropylene with R3Al/TiCl3 instead of R3Al/TiCl4. Furthermore, he also found the polymerization of cyclic olefins with R3Al/ MoCl6 or WCl6, but he misunderstood the reaction mechanism. Subsequent chemists disclosed the correct reaction mechanism : olefin metathesis of a carbene intermediate. A similar mechanism is applied as a Ziegler-Natta polymerization alternative to the insertion mechanism of transition alkylmetals. This Ziegler-Natta catalysts (R3Al-TiCl3/TiCl4) open the reaction types of transmetalation between typical elements/metals and transition metals, which develops into a modern Ni-and Pd-catalyzed cross-coupling reaction. The Ziegler-Natta catalyst reaction of butadiene and acetylene produced rubber as well as conduction polymer. | |||||||
