N-Heterocyclic Carbene Adducts of Alkynyl Functionalized 1,3,2-Dithioborolanes
Autor: Richard Böser, Lars Denker, René Frank
Publikováno v: Molecules, Vol 24, Iss 9, p 1690 (2019)
Alkynyl functionalized boron compounds are versatile intermediates in the areas of medicinal chemistry, materials science, and optical materials. In particular, alkynyl boronate esters [R1−C≡C−B(OR2)2] are of interest since they provide reactiv

Superseding β‐Diketiminato Ligands: An Amido Imidazoline‐2‐Imine Ligand Stabilizes the Exhaustive Series of B=X Boranes (X=O, S, Se, Te)
Autor: Hadi Dolati, Bartosz Trzaskowski, René Frank, Lars Denker
Publikováno v: Angewandte Chemie (International Ed. in English)
Boron reluctantly forms B=X (X=O, S, Se, Te) moieties, which has stimulated the quest for such species in the past few years. Based on the N,N′‐chelating β‐diketiminato ligand (HNacNac), a new amido imidazoline‐2‐imine ligand system (HAmIm

Reactions of a Four-Membered Borete with Carbon, Silicon, and Gallium Donor Ligands: Fused and Spiro-Type Boracycles
Autor: Zeynep Güven, Lars Denker, Hadi Dolati, Daniela Wullschläger, Bartosz Trzaskowski, René Frank
Publikováno v: Chemistry (Weinheim an der Bergstrasse, Germany). 28(32)
Donor-acceptor cyclopropanes or cyclobutanes are dipolar reagents, which are widely used in the synthesis of complex organic (hetero)cycles in ring expansion reactions. Applying this concept to boron containing heterocycles, the four-membered borete

Spectroscopic, XRD, Hirshfeld surface and DFT approach (chemical activity, ECT, NBO, FFA, NLO, MEP, NPA& MPA) of (E)-4-bromo-2-[(4-bromophenylimino)methyl]-6-ethoxyphenol
Autor: Çiğdem Albayrak Kaştaş, Gökhan Kaştaş, Zeynep Demircioğlu, René Frank
Publikováno v: Journal of Molecular Structure. 1191:129-137
In the present work, the compound (E)-4-bromo-2-[(4-bromophenylimino)methyl]-6-ethoxyphenol was synthesized and characterized by spectroscopic (FT-IR and UV–Vis) and single crystal X-ray diffraction techniques. The intermolecular contacts in the co

Benzyl Borane NHC Adducts: Beyond B−C Bond Scission
Autor: Lars Denker, Richard Böser, René Frank
Publikováno v: Chemistry – A European Journal. 25:10575-10579
Benzyl-substituted boronates and borates are widely employed as mild sources in radical or anionic transfer reactions of benzyl entities. In this process the B-C bond to the benzyl moiety is essentially ruptured. In contrast, reactions with retention
