We report the chemical bonding and reactivity of the first example of neutral 18 valence electrons transition metal complexes of beryllium, [BeM(CO)4; M = Fe – Os] in trigonal bipyramidal...

Structure, bonding and reactivity of five-membered N-heterocyclic beryllium compounds (NHBe), BeN2C2H4 (1), and BeN2(CH3)2C2H2 (2) were studied at the M06/def2-TZVPP//BP86/def2-TZVPP level of theory. The molecular orbital analysis indicates that NHBe...

We employed Ph2PN(Ar)PPh2 ligands for the palladium catalyzed C–N cross coupling of a variety of sterically demanding substrates and isolated very good yield of coupling products.

The structure, chemical bonding, and reactivity of neutral 16 valence electrons (VE) transition metal complexes of beryllium, BeM(PMe3)2 (1M‐Be) and BeM(CO)2 (2M‐Be, M = Ni, Pd, and Pt) were studied. The molecular orbital and EDA‐NOCV analysis suggest dative quadruple bonds between the transition metal and beryllium, viz., one Be→M σ bond, one Be←M σ bond, and two Be←M π bonds. The strength of these bonding interactions varies based on the ligands coordinated to the transition metal. The Be←M σ bond is stronger than the Be→M σ bond when the ligand is PMe3, whereas the reverse order is observed when the ligand is CO. This is attributed to the higher π acceptor strength of CO as compared to PMe3. Since these complexes have M–Be dative quadruple bonds, the beryllium center is susceptible to ambiphilic reactivity, as indicated by high proton and hydride affinity values.
