μ-η2:2-s-trans-Butadieneoctacarbonyldiiron(0) – Structural and spectroscopic properties

Germaborene reactivity study – addition of carbon nucleophiles, cycloaddition reactions, coordination chemistry

“…An olefin Fe(CO) 4 complex was found to show CO wavenumbers at 2071, 2005, 1975 cm −1 . 106 The CO stretching frequencies of the germaborene Fe(CO) 4 complex 10 were observed at slightly lower wavenumbers 2051, 1983 and 1960 cm −1 indicating the germaborene as a slightly better donor ligand in comparison to the amino-9-fluorenylideneborane boraalkene and olefin ligand.…”
