Dativ oder nicht dativ?

Abstract

Ist Leberwurst Schweinemarmelade? Hier reagieren die Autoren des Essays Dative Bindungen bei Hauptgruppenelementverbindungen: ein Plädoyer für weniger Pfeile auf die Kritik von Gernot Frenking und berichtigen ihren Essay in einem Punkt.

The boron–boron triple bond? A thermodynamic and force field based interpretation of the N-heterocyclic carbene (NHC) stabilization procedure

“…Anyway, the description of such bonding by arrows is at least strongly misleading, 73 as a more general controversy has already shown. 74 – 76 However, our critical description does not lower the excellent work of H. Braunschweig and G. Robinson, but it increases the understanding of the bonding of their unprecedented compounds.…”

The nature of the NO bond in amine oxides

“…This concept was extended to other C(0) molecules [18,19] and, in a recent review on dative bonds in compounds formed by representative atoms, the authors stated that the dative bond model is important not only for understanding the structure and reactivity of known compounds, but also for guiding some new classes of complexes, such as carbones (CL 2 ) [19]. Although some authors criticize the use of dative bond [20], in recent years the number of papers that have applied this concept in main group chemistry has increased [11,[21][22][23][24][25][26][27].The growing interest in studying N O and related bonds stems from the extensive use of computational chemistry tools to analyze chemical bonds. Among these tools, topological techniques such as quantum theory of atoms in molecules (QTAIM) [28] and electron localization function (ELF) [29] stand out, as well as methods like natural bond orbitals (NBO) [30] and energy decomposition analysis (EDA) [31].…”

Bis(benzoxazol-2-yl)methanides in main group organometallic syntheses and enquiry-based education

“…[151] Particularly the use of arrows to indicate dative or coordinate bonding has been topic of intense discussions. [152][153][154] Apart from Lewis formulas, other forms of representation are also important. Especially in organic chemistry Fischer [155,156] and Newman [157] projections are well established.…”

“…Based on this, it is shortly discussed how to depict different kinds of bonds including intermolecular interactions and a comment on the use of arrows for donor-acceptor type situations is given. [152][153][154] This is followed by the introduction of stereochemistry indicators into skeletal formulas using the wedge-and-dash notation and asterisks to denote chirality centres.…”
