Coupling of Alkynyl(2,4,6-tri-tert-butylphenyl)phosphanes with Cuprous Chloride

Coupling of alkynyl(2,4,6-tri-tert-butylphenyl)phosphanes 2 with n-butyllithium and cuprous chloride gives 3,4-diphospha-1,5-hexadiynes 3 or cuprous chloride complexes 8 of 3,4-bis(phosphinidene)cyclobutenes 5, depending on the bulkiness of the substituen

3H-PHOSPHAALLEN-ALKINYL-1H-PHOSPHAN-TAUTOMERE

The title compounds are prepared for the first time by reaction of 2,4,6-tris(tert-butyl)phenylchlorophosphane with Li-resp.Mg-acetylides

Low Coordinated Phosphorus Compounds, 56. - Valence Isomerisation of a 3,4-Diphospha-1,5-hexadiyne with Formation of a 3,4-Bis(phosphamethylene)-1-cyclobutene

Reaction of ethynylphosphane 1 with BuLi leads to 3,4-diphospha-1,5-hexadiyne 4, which undergoes valence isomerisation to 3,4-bis(phosphamethylene)-1-cyclobutene 6.The structure of 6 has been confirmed by X-ray structure determination.
