TLDR
In this article, the Grignard-Verbindung of Dichlor-diphenylmethane with organosilicon, organogermanium, and organotin chlorides yields 9.10-dihydroanthracene derivatives (3-13) which contain a hetero atom instead of C-9.
Abstract
Durch Umsetzung der Grignard-Verbindung 1 aus o.o′-Dichlor-diphenylmethan mit Organosilicium-, -germanium- und -zinnchloriden entstehen Dihydroanthracenderivate (3–13), die statt C-9 ein Heteroatom enthalten. Substitutions- und Austauschreaktionen in 9- und 10-Stellung sowie Versuche zur Aromatisierung werden beschrieben. 1H-NMR-Spektren sichern die Struktur der dargestellten Heterocyclen und erklaren vorliegende Konformationsgleichgewichte. 9-Sila-, -Germa-, and -Stanna-dihydroanthracenes Reaction of the Grignard compound 1, obtained from o.o′-dichlorodiphenylmethane, with organosilicon, organogermanium, and organotin chlorides yields 9.10-dihydroanthracene derivatives (3–13) which contain a hetero atom instead of C-9. Further substitution and exchange reactions in positions 9 and 10 are described as well as attempts at aromatisation. 1H n.m.r. spectra supply proof for the structure of these new heterocycles and explain the existence of conformational equilibria.

Aryl(hydro)boranes: versatile building blocks for boron-doped π-electron materials

TL;DR: Key structural motifs and reactivity patterns of recently developed aryl(hydro)boranes are discussed and it is shown how these have been used for the synthesis of macromolecular organoboranes through hydroboration polymerisation, ring-opening polymerisation and condensation polymerisation protocols.

Neue Element‐Kohlenstoff‐(p‐p)μ‐Bindungen

Peter Jutzi
- 01 Apr 1975 - 
TL;DR: In den letzten Jahren wurden μ-Systeme dargestellt, die neuartige (p-p)μ-Bindungen zwischen Kohlenstoff and Elementen aus der dritten, vierten oder funften Hauptgruppe des Periodensystems enthalten und grostenteils nach der klassischen Doppelbindungsregel nicht existent sein sollten.

Synthesis and Comparative Characterization of 9‐Boraanthracene, 5‐Boranaphthacene, and 6‐Borapentacene Stabilized by the H2IMes Carbene

TL;DR: Comparative structural, photophysical, and redox properties reveal narrow HOMO-LUMO gaps relative to the all-carbon acene analogues.

The Preparation of Organolithium Compounds by the Transmetalation Reaction. I. Vinyllithium1,2

TL;DR: In this article, the use of vinyllithium in the preparation of previously known vinyl compounds, as well as of the new STAB(CH = CH/sub 2/)/sub 4/!/sup -/ and STAB (CH ~ CH/ sub 2/ ) (C/sub 6/H/sub 5/)/ sub 3/!/Sup -/ ions, is described.

Addition des phénylgermanes et phénylchlorogermanes sur quelques composés carbonyles insaturés

TL;DR: In this paper, the steric hindrance around the double ethylenic bond directs the addition of triphenylgermane to the carbonyl group of 2-methyl-2-hepten-6-one and mesityl oxide (l,4-addition).
