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

Chemistry of sterically protected bis(phosphinidene)-cyclobutenes

Sterically protected low-coordinated phosphorus-containing cyclobutenes were prepared and characterized as well as [4]radialenes. The reactions were studied involving E/Z isomerization, transition-metal complex formation, and coupling reactions catalyzed

X-Ray structure analyses of diphosphinidenecyclobutene and its chelate type tetracarbonylmolybdenum(0) complex

The structure of tetracarbonylmolybdenum(0) has been analyzed by X-ray crystallography.The structure of the free ligand, diphosphinidenecyclobutene, has also been analyzed and compared with that of the metal carbonyl complex.

Preparation of Sterically Protected 3,4-Bis(phosphinidene)cyclobutenes and Their Isomerism

Sterically protected bis(phosphinidene)cyclobutenes were prepared starting from the diphosphane and their isomerism involving a 1,6-diphosphahexa-1,2,4,5-tetraene intermediate, which is both cumulative and conjugated, was studied.X-Ray crystallographic st
