 Title    Darstellung von Alkylmethylphenylphosphanen nach der Methode von Hewertson und Watson Preparation of Alkylmethylphenylphosphines by the Method of Hewertson and Watson  
 Abstract    The reaction of C 6 H 5 (CH 3)PNa with some alkyl halides in liquid ammonia was studied. The resulting phosphines were characterized by elemental analyses, NMR spectra, and by the reaction with trimethylsilyl azide giving trimethylsilylimino triorganophosphoranes.

 Title    Darstellung und [l+4]-Cycloaddition von Methylthio-chlorophosphanen RP(Cl)SMe (R = Me, Et, Ph) Preparation and [l+4]-Cycloaddition of Methylthio-chlorophosphanes RP(Cl)SMe (R = Me, Et, Ph)  
 Abstract    The methylthio-chlorophosphanes RP(Cl)SMe [R = Me (1). Et (2). Ph (3)] are prepared in good yields (62—65%) by condensation reactions of the corresponding dichlorophosphanes RPC12 with methanethiol in the presence of trimethylamine (molar ratio 1:1:1). 1 and 3 have been used to produce 3-phospholene sulfides in a one-pot process by reaction with 1,3-dienes at 70 to 100 °C. Reaction proceeds via [1 +4]-cycloadducts, which in suitable cases can be isolated and used for the preparation of the corresponding 3-phospholene oxides. New compounds were characterized by elemental analysis and spectroscopic investigations (NMR. MS).

 Title    [l,4,2]Diazaphospholidine [l,4,2]Diazaphospholidines  
 Abstract    Bis(diethylamino)phosphanylacetylen reacts with N.N'-dimethyl thiourea to give 2-diethyl-amino-l,4-dimethyl-3-methylene-[l,4,2]diazaphospholidine-5-thion (2) besides the [1.3.4]thi-azaphospholidine (1). The latter compound is converted into 2 by heating. Reaction of 2 with various reagents yields other members of the title compound class. All new compounds are characterized by some reactions and their NMR and IR spectra. In addition, the results of an X-ray structure analysis of 2-diethylamino-l ,4-dimethyl-3-methylene-2-thioxo-[l ,4.2]diazaphos-pholidine-5-thion (5) are reported.

 Title    Rhodium-zentrierte Bildung eines Cyclobutenyl-Liganden und Umlagerung in einen Cyclopentadienyl-Komplex Rhodium-centered Formation of a Cyclobutenyl Ligand and Rearrangement to a Cyclopentadienyl Complex  
 Abstract    Cyclization of two diphenylacetylene molecules occurs if [(cod)RhCl] 2 (cod = 1.5-cyclooc-tadiene) is treated with methyllithium in the presence of tolane. The isolated (cod)Rh complex 2 contains an e*o-methyl-tetraphenylcyclobutenyl ligand and was characterized by X-ray diffraction analysis. Thermolysis of 2 in acetonitrile causes ring expansion of the methylcyclobutenyl unit with formation of the tretraphenylcyclopentadienyl complex 3 together with 3-methyl-tet-raphenylcyclobutene. Mechanistic aspects are discussed as well as spectroscopic data of the new compounds.

 Title    Lineare Oligophosphaalkane, XX [1] Alkalimetall-und Trimethylsilylderivate PH-funktioneller Methylenbisphosphane Linear Oligophosphaalkanes, XX [1] Alkali Metal and Trimethylsilyl Derivatives of PH-Functional Methylenebisphosphanes  
 Abstract    The synthesis of the trimethylsilyl derivatives of the PH-functional methylenebisphosphanes, R 2 ^"(Me 3 Si)"P—CH 2 —PR(SiMe 3) (R = Me. /Pr. tBu. Ph. 2.4.6-Me 3 C (,H 2 ; n = 0. 1) is reported. In the Li-phosphides R 2 _"Li"P — CH 2 — PUR used as reactive intermediates, a monomer-oligomer association equilibrium causes a rapid Li-exchange as indicated by the solvent and temperature dependent ^PI'H} and 7 Li NMR spectrum of (/Pr) 2 P-CH 2 -P(/Pr)Li in various solvents (Et : 0. THF and MTHF) in the temperature range from 30 to -110 °C. For the syntheses of the Me-and Ph-substituted PH-functional methylenebisphosphanes R 2 P-CH 2 -PRH and RHP-CH 2 -PRH (R = Me, Ph) the chlorophosphane CKP —CH 2 —PC1 2 is used as a starting material. Bifunctional substituents (Ph —N—N —Ph and Me —N—CO —N—Me) are employed for the first time as protect-ing groups to block one or two PCl-functions in C1T—CIL—PCI-,. Cleavage of the PN-bonds in the five membered ring systems RP-CH 2 -PR-N(Ph)-N (Ph) (R = Me. Ph) with HCl affords the P-substituted methylenebis-chlorophosphanes RC1P—CH 2 — PC1R in satisfactory yields. The compounds have been characterized by 'H. I3 C{ 'H} and 3! F*{'H}NMR spectroscopy. With-in homologous substitution series of methylenebisphosphanes, e.g. R 2 P—CH 2 —PR 2 _"H" the coupling constants 2 /(PP) seem to reflect conformational changes at the PCP-skeleton.

 Title    Synthese und Struktur des ersten dreigliedrigen Arsen—Phosphor—Platin-Ringes Synthesis and Structure of the First Three-Membered Ring Containing Arsenic, Phosphorus and Platinum  
 Abstract    -butylphenylphosphane reacts with CpFe(C,H4AsCl2) in the presence of DBU to yield CpFe[C5H4As=PC6H2(f-Bu)?l. The reaction of this arsaphosphene with (Ph3P)2PtC2H4 yields CpFe[C5H4As—P[C6H2(r-Bu)3]Pt(PPh3)2], a compound with a three-membered ring containing arsenic, phosphorus and platinum.
