Stabilisation effects of ferrocenylalkyl groups on hydrides of heavier main group elements
… extreme instabilities. Some related primary phosphanes, [CpFeC₅H₃(CH₂OH)(CH₂PH₂)], RcCH₂PH₂ and Fc(CH₂)₆PH₂∙BH₃, phosphane oxide, FcCH₂P(O)H₂, and phosphinic acid, FcCH₂P(O)(OH)H, were also synthesised and reported. The X-ray crystal structures of Fc(CH₂)₆PH₂∙BH3 and FcCH₂SeCN are also …

Dipyrazolylphosphanes in Condensation and P–N/P–P Bond Metathesis Reactions
… A crucial point in the chemistry of polyphosphanes is of course the formation of P–P bonds. Numerous synthetic procedures are established and reviewed including salt metathesis,4a,14 dehalosilylation15 and dehalostannylation16 reactions, base promoted dehydrohalogenation reactions17 and …

Novel aza-arylphosphane ligands for ruthenium catalyzed anti-Markovnikov hydration of terminal alkynes
… synthesis of C6-tert-alkyl- and C6-aryl-pyridylphosphanes, as well as selected aza-arylphosphanes with different substitution pattern by newly developed copper- or nickel-catalyzed cross-coupling reactions. In a second part, these new phosphanes were used as ligands (L) for the synthesis of …

Construction and Application of Reference Scales for the Characterization of Cationic Electrophiles and Neutral Nucleophiles
… new classes of nucleophiles like enamines, phosphanes and phosphites, and pyridines as well as by adding new electrophiles. Kinetic data for electrophile-nucleophile combinations were used for discussing structure-reactivity relationships, as well as for the analysis of mechanistic aspects. …

Synthese von planar chiralen Imidazoliumsalzen, ihren Metall-Carbenkomplexen und deren Verwendung in der asymmetrischen Katalyse
… an interesting alternative to the commonly used phosphanes. Starting from enantiopure pseudo-ortho-dibromo[2.2]paracyclophane, different paracyclophanylimidazolium salts were synthesized, and either subsequently transformed to their metal complexes or directly used in catalytic reactions. Hence, …
