坏戊二烯基铊(Ⅰ)(简作CpTl,Cp≡η~5-C_5H_5)是一个重要的金属有机试剂,和环戊二烯基锂、钠、钾类似,可向金属化合物中引入茂基。但它还有另一些特点,即在空气中很稳定,便于拿取、使用和保存;碱性较弱,可用于不适应强碱的合成场合。关于铊的有机衍生物,包括铊(Ⅰ)和铊(Ⅲ),在1930年就已有所研究,1956年首次制得:CpTl,1960年以后有机铊化学发展很快,对三价铊有机物的化学已有评论,但对铊(Ⅰ)较少,早期评述见文献[2]。
The bad pentadienyl thallium (Ⅰ) (abbreviated as CpTl, Cp≡η ~ 5-C_5H_5) is an important metal organic reagent. Like cyclopentadienyl lithium, sodium and potassium, . But it also has other characteristics, that is stable in the air, easy to take, use and preservation; alkaline is weak, can be used to adapt to alkali synthesis occasions. The organic derivatives of thallium, including thallium (I) and thallium (III), have been studied in 1930 and were first produced in 1956: CpTl. The chemical development of organic thallium rapidly after 1960, The chemistry has been reviewed, but less for thallium (I), an early review see [2].
