Abstract When bismuth atoms are incorporated into cyclic organic systems, this commonly goes along with strained or distorted molecular geometries, which can be exploited to modulate the physical and chemical properties of these compounds. In six‐membered heterocycles, often accompanied by oxygen, sulfur nitrogen as a second hetero‐element. work, we present first examples rings, in two CH units replaced BiX moieties (X=Cl, Br, I), resulting dihydro‐anthracene analogs. Their behavior chemically reversible reduction reactions is explored, aiming at generation dibisma‐anthracene (bismanthrene). Heterometallic compounds (Bi/Fe, Bi/Mn) introduced potential bismanthrene surrogates, supported bismanthrene‐transfer selenium. Analytical techniques used investigate reported include NMR spectroscopy, high‐resolution mass spectrometry, single‐crystal X‐ray diffraction analyses, DFT calculations.

Published: May 8, 2023

The reactivity of a literature-known, ring-strained cationic bismuth amide toward the unsaturated substrates RN═C═NR, CS2, and acrylonitrile is reported (R = iPr, Cy, pTol). Subtle changes in polarity reaction medium (THF vs pyridine) can be exploited to selectively address two different pathways. Either dinuclear nature starting material preserved, only one substrate molecule per atoms incorporated into product, an aryl migration possible or well-defined mononuclear compounds with Bi/substrate ration 1:1 are observed. These findings correlate unexpected increase species, when solvent increased from THF pyridine, likely connected nuclearity material.
