Abstract
Sterically protected low-coordinate organophosphorus compounds such as diphosphenes, phosphaalkenes, 1,3-diphosphaallenes, 1-phosphaallenes, phosphaalkynes, and 3,4-diphosphinidenecyclobutenes are described, which are stabilized with an extremely bulky 2,4,6-tri-t-butylphenyl (Mes*) group. The structures, physical and chemical properties are highly interesting, because they are unusual phosphorus compounds.
