Insertion of germylenes into Ge–X bonds giving molecular oligogermanes: theory and practice

Germanium Complexes with ONO Tridentate Ligands: O-H Bond Activation Control According to DFT Calculations

“…It should be noted that the parameters used for the calculations (B3LYP/DGDZVP for structure optimization) are correct; the main calculated structural parameters correlate well with the XRD data. In continuation of our research (see above, Schemes 1 and 3) into germylenes [33][34][35][42][43][44], this work presents our theoretical results on their synthesis to understand how the oxidation state of the central atom is regulated by the steric properties of organic ligands (1-H, 1-Me vs. 2-H, 2-Me), the oxidation state of which remains unchanged.…”

“…Tetrylenes [3][4][5][6][7]-heavier carbene analogs-have recently attracted significant attention [8][9][10][11][12][13][14][15][16][17][18][19][20]), primarily due to their possible application as analogs of transition metals in catalysis [21][22][23], in activation of small molecules [24][25][26][27][28][29][30], as ligands [31,32], in possible synthesis of derivatives with E-E bonds [33][34][35], reagents for synthesis [36][37][38][39] or precursors [40][41][42] in material chemistry. These species are reactive and unstable; to stabilize them, the introduction of bulky groups (kinetic stabilization) or polydentate ligands (thermodynamic stabilization) is used.…”
