SILICIUMVERBINDUNGEN MIT STARKEN INTRAMOLEKULAREN STERISCHEN WECHSELWIRKUNGEN XII. SYNTHESE UND MOLEKUELSTRUKTUR DES 1,2-BIS(2,4,6-TRI-t-BUTLYPHENYL)-3,3-DI-t-BUTYL-1,2,3-DIPHOSPHASILIRANS

The reaction of di-t-butyldiiodosilane with excess lithium naphthalenide followed by treatment with dichloro(2,4,6-tri-t-butylphenyl)phosphane (ArPCl2) leads to the diphosphene ArP=Ar, the air-stable compound 1,2-bis(2,4,6-tri-t-butylphenyl)-3,3-di-t-butyl-1,2,3-diphosphasilirane (3), and other products.The X-ray structure analysis reveals slightly elongated Si-P and P-P bond lengths of about 224.3 and 223.4 pm, respectively.The steric crowding of the three-membered heterocycle causes a puckering of the phenyl rings and a bending of the ortho-t-butyl groups out of the ring planes.

STANNYLENE AND GERMYLENE AS POWERFUL DECHLORINATED REAGENTS. NEW ROUTE TO DIPHOSPHENE.

Dichlorophosphines RPCl2 are reduced to the corresponding phosphorus-I compounds by the stannylene Me2Si(NtBu)2Sn: (1) or by the germylene GeI2 (2); in the case of the reaction of (5) with (1), bis(2,4,6-tri-tert-

Reaction of the Diphosphene ArP=PAr (Ar = 2,4,6-But3C6H2) with Sulphur: Isolation and X-Ray Structure of the Diphosphene Monosulphide

The diphosphene ArP=PAr (Ar = 2,4,6-But3C6H2) reacts with elemental sulphur to give the stable monosulphide ArP(S)=PAr (2) whose structure was confirmed by an X-ray analysis; when treated with hexamethylphosphorous triamide, (2) reverts to the starting diphosphene but thermal and photochemical isomerisation of (2) gives the thiadiphosphirane Ar-cyclo-Ar.

Wavelength- and Temperature-dependent Photolysis of a Diphosphene. Generation of 2,4,6-Tri-t-butylphenylphosphinidene and E/Z Isomerization

A phospha-indane derivative was obtained via intramolecular C-H insertion of the phosphinidene generated as an intermediate by the photolysis of E-1,2-bis(2,4,6-tri-t-butylphenyl)diphosphene whereas the photolysis through a Pyrex filter at -40 o/sup

The Question of 'Open' or 'Closed' Bimetallic Phosphinidene (and Heavier Congeneric) Complexes

The reaction of ArPCl2 (Ar = 2,4,6-But3-C6H2) with Na affords the 'open' phosphinidene complex, Co2(μ2-PAr)(ν-C5H5)2(CO)2, the structure of which has been determined by X-ray crystallography.

Synthesis and Theoretical Investigation of Diphosphastannylenes

The factors affecting the stabilization of diphosphastannylenes, such as substituent size, steric demand, and type of substituent (aryl, alkyl, silyl) were investigated via a comprehensive DFT and experimental investigation. The influence of various substituents (H, Me, tBu, Ph, TMS, Hyp = (Si(SiMe3)3)) on the pyramidalization of the phosphorus centers and cone angle determination of those substituents were carried out. Through these considerations, ligand systems capable of isolating a stable Sn(II) species were determined. Synthetic work led to the isolation of dimeric supermesityl(trimethylsily)phosphanides, 2,4,6-tris(t-butyl)phenyl trimethylsilyl lithium phosphanide, 2,4,6-tris(t-butyl)phenyl trimethylsilyl potassium phosphanide, and one hypersilylphosphanide [HypP(SiMe3)K·DME]. In addition to that, a novel monomeric diphosphastannylene [HypP(SiMe3)]2Sn was isolated as well as confirmed by experimental and calculated NMR data and single crystal X-ray analysis.

Platinum(II) complexes of some unsymmetrical diphosphenes

Reaction of the unsymmetrical diphosphene Ar*P=PArF1 (Ar*?=?2,4,6-tBu3C6H2, ArF?=?2,4,6-(CF3)3C6H2) with the dimeric platinum(II) species trans-[Pt(PEt3)Cl(μ-Cl]2led initially to the formation of two different monomeric Pt(II) complexes trans-[Pt(PEt3)Cl2(Ar*P=PArF)] 2 and trans-[Pt(PEt3)Cl2(ArFP=PAr*)] 3, where the underlined phosphorus atom coordinates to Pt. These were readily identifiable by31P NMR solution-state spectroscopy, but attempts to separate them by column chromatography were unsuccessful. When the reaction was repeated on a larger scale, a third complex cis-[Pt(PEt3)Cl2(ArFP=PAr*)] 4 was detected in solution, with P-ArFbound to Pt. Calculations of energies and31P NMR chemical shifts confirm that this species is expected to be the thermodynamically most stable monomeric reaction product. For comparison, we have also prepared the analogous Pt(II) complex trans-[Pt(PEt3)Cl2(Ar*P=PAr*)] 6 of the symmetrical diphosphene Ar*P=PAr* 5, and obtained its31P NMR parameters in solution. The mixed diphosphene Ar′P=PArF7 (Ar′?=?2,6-(CF3)2C6H3) reacts with the same platinum(II) dimer to yield a single cis-complex 8. Calculations have enabled us to assign the31P chemical shifts of this unsymmetrical diphosphene 7, and to show that the Ar′ group is coordinated to Pt in the unique product cis-[Pt(PEt3)Cl2(Ar′P=PArF)] 8.

Synthetic strategies to bicyclic tetraphosphanes using P1, P2 and P4 building blocks

Different reactions of Mes? substituted phosphanes (Mes? = 2,4,6-tri-tert-butylphenyl) led to the formation of the bicyclic tetraphosphane Mes?P4Mes? (5) and its unknown Lewis acid adduct 5·GaCl3. In this context, the endo-exo isomer
