SUBJECTS: Anions, Aromatic compounds, Hydrocarbons, Ligands, Phenyls. Abstract. One century ago, Franz Hein started the highly regarded arylchromium chemistry with his initial publication in January 1919.
This essay brings the story of the bis (arene) complexes of Cr (0) and Cr (I), starting with the early work of Hein and continuing on to the present day. Chromium is a transition metal in group 6 of the periodic table, with a ground-state electron configuration of [Ar]3d 5 4s 1.
Phenylchromium(III) Chemistry Revisited 100 Years after Franz Hein (Part III): From (Ar) 3–n CrCl n (L) x (Ar = Ph, p‑F‑C 6 H 4, C 6 D 5; n = 0, 1, 2; L = thf, dme, tmeda, 12C4) to Bis(π-arene)chromium Complexes
On the basis of early studies of Franz Hein (1892–1976) on (poly)phenylchromium(III) compounds of the type Ph x CrX 3–x (L) n (1 ≤ x ≤ 3) and polyphenylchromate(III) derivatives of the type (L) n M x–3 CrPh x (3 ≤ x ≤ 6) with L being an ether like tetrahydrofuran (thf), 1,2-dimethoxyethane (dme), or tetrahydropyran (thp), we ...
