Synthetic and reaction chemistry of heteroatom stabilized boryl and cationic borylene complexes.

Adding Borylene Ligands to the Organometallic Toolbox

INTRODUCTION Complexes containing metal-boron bonds are relatively new to organometallic chemistry. Just over 20 years ago, the first crystallographically characterized complexes containing a transition metal-boron bond were reported. Boron is typically encountered in the +3 oxidation state, and boron species commonly serve as Lewis acids via their vacant p-orbital. Indeed, metal borane complex...

Side-on coordination of boryl and borylene complexes to cationic coinage metal fragments.

The M-(η2-BMn) complex [(η5-C5H5)(OC)2Mn{μ-B(Cl)(tBu)Au(PPh3)}] (2) can be functionalized via halide substitution reactions to afford isostructural complexes [(η5-C5H5)(OC)2Mn{μ-B(R)(tBu)Au(PPh3)}] (R = Ph, CCPh and NCS). It also reacts with coinage metal complexes [MCl(PPh3)] (M = Au, Ag and Cu) in the presence of halide abstraction reagents to afford borylene-bridged heteromultinuclear comple...

Effects of structure and number of Heteroatom on the π-π stacking interactions of benzene with N-substituted coronenes: A theoretical study

Stability of the π-π stacking interactions in the Ben||N-substituted-coronene complexes was studied using the computational quantum chemistry methods (where Ben is benzene and || denotes π-π stacking interaction, and N-substituted-coronene is coronene molecule which substituted with different number of N atoms). The results reveal simultaneous effects of structure and number of Heteroatom on th...

Surface-grafted Europium and Erbium Complexes of the 12-Tungstosilicate Heteropolyoxometalate: A Synthetic and Structural Investigations

The hydrothermal synthesis of two new inorganic-organic hybrid materials in which PDA (PDA = 1,10-phenanthroline-2,9-dicarboxylate) is connected to a well-defined Keggin-type polyoxometalate anion (POM) and a Ln(III) cation (POM = [SiW12O40]4−; Ln = Eu3+ (1), Er3+ (2)), are reported. These hybrids are characterized by elemental analyses, IR spectra and single-crystal X-ray diffraction. Single-c...
