Abstract

The steric hindrance of ligands plays a crucial role in the structures of carboranyl phosphorus(I) compounds as evidenced by experimental and theoretical studies.

Room temperature stable E,Z-diphosphenes: their isomerization, coordination, and cycloaddition chemistry

Jieli Lin, Shihua Liu, Jie Zhang, Hansjörg Grützmacher, Cheng-Yong Su and Zhongshu Li

Chem. Sci., 2023,14, 10944-10952

Abstract

N-Heterocyclic vinyl substituted diphosphenes 2b in both E- and Z-isomers have been isolated and crystallographically characterized. They exhibit reversible photo- and thermally stimulated E ↔ Z isomerization mimicking their carbon analogue.

Abstract

A cationic rhodium complex with a bidentate ligand including a diphosphene (P [double bond, length as m-dash] P bond) and a phosphineborane was synthesized and characterized. The reactivity and the catalytic activity of this complex were investigated.

Abstract

Macrocyclic bis-diphosphenes, formally heavier derivatives of macrocyclic azobenzenes, are accessed for the first time.

Selective monooxygenation of diphosphenes with molecular oxygen

Yuria Kawase, Shota Tsujimoto, Tomohiro Obayashi, Satoshi Kimura, Kanta Ito, Shotaro Ikoma, Kei Ota, Daisuke Hashizume and Tsukasa Matsuo

Dalton Trans., 2024,53, 1956-1960

Abstract

The O₂ splitting mediated by the bulky Rind-based diphosphenes leads to the clean formation of the diphosphene oxides with (O [double bond, length as m-dash] )PP moieties.
