三明治化合物

Sandwich compound

在有机金属化学中,三明治化合物是一种化合物,其特征在于金属通过触觉共价键结合到两个芳烃配体上。 芳烃具有式C n H n,取代的衍生物(例如C n(CH 3)n)和杂环衍生物(例如BCnHn + 1)。 因为金属通常位于两个环之间,所以称为“夹层”。 一类特殊的三明治复合物是金属茂。 在二十世纪五十年代中期,J.D.Dunitz,L.E。的报告中引入了三明治化合物的有机金属术语。 奥格尔和R.A. 富士通过X射线晶体学证实了二茂铁的结构。 Robert Burns Woodward几年前提出了正确的结构。 该结构有助于解释有关二茂铁构象异构体的谜题,该分子的特征是夹在两个平行环戊二烯基环之间的铁原子。 该结果进一步证明了X射线晶体学的功能,并加速了有机金属化学的生长。 In organometallic chemistry, a sandwich compound is a chemical compound featuring a metal bound by haptic covalent bonds to two arene ligands. The arenes have the formula CnHn, substituted derivatives (for example Cn(CH3)n) and heterocyclic derivatives (for example BCnHn+1). Because the metal is usually situated between the two rings, it is said to be "sandwiched." A special class of sandwich complexes are the metallocenes. The term sandwich compound was introduced in organometallic nomenclature in during the mid-1950s in a report by J.D. Dunitz, L.E. Orgel and R.A. Rich, who confirmed the structure of ferrocene by X-ray crystallography. The correct structure had been proposed several years previously by Robert Burns Woodward. The structure helped explain puzzles about ferrocene's conformers, the molecule features an iron atom sandwiched between two parallel cyclopentadienyl rings. This result further demonstrated the power of X-ray crystallography and accelerated the growth of organometallic chemistry.
