- Abstract
It is demonstrated that backbone chloro(phenyl)phosphanyl‐substituted imidazole‐2‐thiones 3 (N‐R = Me, Et, nBu) can be easily synthesized which allow for a selective access to tricyclic 1,4‐diphenyl‐1,4‐dihydro‐1,4‐diphosphinines 5 via reaction with LDA. Furthermore, new examples for preferred substitution reactions are provided that occurred when KHMDS was used thus yielding P–N(SiMe3)2 substituted derivatives 4. The new P–Ph substituted tricyclic 1,4‐dihydro‐1,4‐diphosphinine derivatives 5 were successfully employed to generate tricyclic bis‐phosphanides 6 using potassium in THF, and the formation of 6 was proven via quenching with excess of n‐butyl iodide to give P–nBu substituted derivatives 7 obtained as mixture of cis and trans isomers.
