A new family of long-lived alkane σ-complexes of the type (L(OEt))Re(CO)(2)(alkane) [alkane = cyclopentane, cyclohexane, pentane; L(OEt) = cyclopentadienyltris(diethylphosphito)cobaltate(III)] has been observed using both IR and NMR spectroscopies and computationally interrogated with DFT methods. The oxygen-rich coordination spheres makes these complexes perhaps more relevant as models for intermediates in metal oxide mediated hydrocarbon transformations than other known alkane σ-complexes.
已通过红外和核磁共振光谱以及密度泛函理论(DFT)方法的计算研究观察到了新型长寿命链烷 σ-配合物,其类型为 (L(OEt))Re(CO)(2)(链烷) [链烷 = 环戊烷、环己烷、戊烷;L(OEt) = 环戊二烯基三(二乙基膦酸酯)钴(III)]。富氧配位球使这些配合物可能更适合作为金属氧化物介导的碳氢化合物转化中间物的模型,而不是其他已知的链烷 σ-配合物。
