3H‐Phosphaallenes Revisited: Facile Synthesis by Hydroalumination of Alkynylphosphines and β‐Elimination, Stability and Trapping of Transient Species by Coordination to Transition Metal Atoms
Autor: Jonas C. Tendyck, Werner Uhl, Hans Klöcker, Lukas Keweloh, Alexander Hepp
Publikováno v: Chemistry – A European Journal. 25:4793-4807
A facile method for the efficient synthesis of 3H-phosphaallenes, R-P=C=C(H)-R', is presented, which comprises treatment of dialkynylphosphines with dialkylaluminium hydrides (hydroalumination) and elimination of aluminium alkynides from intermediate

Aspects of Phosphaallene Chemistry: Heat-Induced Formation of 1,2-Dihydrophosphetes by Intramolecular Nucleophilic Aromatic Substitution and Photochemical Generation of Tricyclic Phosphiranes
Autor: Lina Schürmann, Werner Uhl, Marcus Layh, Ernst-Ulrich Würthwein, Hans Klöcker, Alexander Hepp, Jonas C. Tendyck
Publikováno v: The Journal of organic chemistry. 85(22)
3H-Phosphaallenes are accessible on a new and facile route and show a fascinating chemical behavior. The thermally induced rearrangement of Mes*P═C═C(H)R′ (R′ = tBu, Ad) afforded by C–H activation,...

A P−H Functionalized Al/P Frustrated Lewis Pair: Substrate Activation and Selective Hydrogen Transfer
Autor: Werner Uhl, Ernst-Ulrich Würthwein, Hans Klöcker, Lukas Keweloh
Publikováno v: Angewandte Chemie International Edition. 55:3212-3215
Hydroalumination of an alkynylphosphine gave an unprecedented P-H functionalized frustrated Lewis pair (FLP). The reactive P-H group does not influence the typical FLP properties, but the activation of substrates follows a new reaction pattern involv

Hydroalumination of alkynyl-aminophosphines as a promising tool for the synthesis of unusual phosphines: P–N bond activation, a transient phosphaallene, a zwitterionic AlP2C2heterocycle and a masked Al/P-based frustrated Lewis pair
Autor: Hans Klöcker, Werner Uhl, Marcus Layh, Alexander Hepp
Publikováno v: Dalton Transactions. 45:2031-2043
Treatment of the new alkynyl-chlorophosphine, Mes-P(Cl)-C ≡ C-CMe3, with LiNR2 afforded various unprecedented aminophosphines, Mes-P(NR2)-C ≡ C-CMe3, which showed a fascinating diversity in their reactivity towards H-Al(t)Bu2. NMe2 and NEt2 deriv

Molecular Structures of Dimeric and Trimeric Dineopentylaluminum Hydride and Trimeric Diphenylaluminum Hydride
Autor: Andrej Vinogradov, Hans Klöcker, Werner Uhl, Hauke Westenberg, Jana Backs, Christian Appelt
Publikováno v: Zeitschrift für anorganische und allgemeine Chemie. 640:106-109
The synthesis of dineopentylaluminum hydride, H-Al(CH2CMe3)2, is known in the literature since 1988. We determined the crystal structure of this important starting material and found different ring sizes with dimeric versus trimeric formula units. Th
