Functionalization of Pentaphosphorus Cations by Complexation†
TLDR
Reactions with [Et4N]X (X=CN and Cl) give unprecedented cyano‐ and chloro‐functionalized complexes, while organo‐ functionalization was achieved with CyMgCl. Expand
Formation of a Carbene–Phosphinidene Adduct by NHC-Induced P–P Bond Cleavage in Sodium Tetramesityltetraphosphanediide
The reaction of [Na2(thf)4P4Mes4] (1) (Mes = 2,4,6-Me3C6H2) with 1,3-dimethylimidazolin-2-ylidene (Me2Im) or the corresponding imidazolium iodide ([Me2ImH]I) leads to P–P bond cleavage and formationExpand
Versatile Coordination Modes of Triphospha-1,4-pentadiene-2,4-diamine.
TLDR
The transition-metal complexes were characterized by multinuclear NMR spectroscopy, mass spectrometry, infrared spectroscopic, and X-ray crystallography and the mechanism of the rearrangement was supported by quantum-mechanical calculations. Expand
Unusual Reactivity of Sodium Tetramesityltetraphosphanediide towards Cyclohexyl Isocyanide.
TLDR
Molecular structures of compounds 3, 4, and 5 were obtained and with catalytic amounts of AgBF4, 2 was the major product. Expand
Phosphaindazole: A Phosphorus–Carbon Aromatic Heterocycle
A straightforward synthetic route to a novel phosphorus–carbon heterocycle, namely, phosphaindazole, which is the phosphorus analogue of indazole or indene, was developed from sodiumExpand
Basicity of N‐(Tetramesityltetraphosphacyclopentylidene)cyclohexylamine: An Unusual Diphospha(III)guanidine Derivative
The nitrogen atom in cyclic hetero-oligophosphane cyclo-P4Mes4C(NCy) (1) can be protonated with HCl or HBF4. The resulting cation was isolated as the BF4-, AlCl4- and GaCl4- salts and characterisedExpand
Electrophile-induced nucleophilic substitution of the nido-dicarbaundecaborate anion nido-7,8-C2B9H12- by conjugated heterodienes.
TLDR
These reactions are the first examples in which compounds (here heterodienes) that unite the functionalities of both hydride acceptor and nucleophilic site react with 1 in a bimolecular fashion. Expand
A Sixteen-Membered Au8 P8 Macrocycle Based on Gold(I) and Diphospha(III)guanidine.
The reaction of cyclo-P4 Mes4 C(NCy) (1) with two equivalents of [AuCl(tht)] (tht=tetrahydrothiophene) resulted in the formation of unusual sixteen-membered Au-P macrocycle 2. This macrocycleExpand
Making and breaking of phosphorus–phosphorus bonds
Abstract In contrast to their mostly unstable isolobal carbon counterparts, oligophosphanide anions, such as M(cyclo-P5tBu4) (M=Li, Na) and M2(P4R4) [M=Na, K; R=Ph, tBu, 2,4,6-Me3C6H2 (Mes)], haveExpand
