 Title    Übergangsmetall-substituierte Diphosphene, XIV [1]  
 Abstract    Zur Reaktivität des Diphosphenylkomplexes (i/ 5 -C 5 Me5)(CO) 2 Fe—P=P—Ar (Ar = 2,4,6-r-Bu 3 C 6 H 2) gegenüber Schwefel, Selen und Tellur. Synthese und Struktur des ersten Thioxo-A s -diphosphenyl-Komplexes (!7 5 -C 5 Me 5)(CO) 2 Fe-P(=S)(=P-Ar) Transition Metal Substituted Diphosphenes, XIV [1] On the Reactivity of the Diphosphenyl Complex (?; ; '-C5Me5)(CO) 2 Fe-P=P-Ar (Ar = 2,4,6-J-Bu 3 C 6 H 2) towards Sulfur, Selenium, and Tellurium. Synthesis and X-Ray Structure Analysis of the First Thioxo-A 5 -diphosphenyl Complex (>/ 5 -C 5 Me 5) (CO) 2 Fe -P(=S)(=P -Ar) The diphosphenyl complex (?7 5 -C 5 Me 5)(CO) 2 Fe-P=P-Ar (la) (Ar = 2,4,6-rm-Bu 3 C 6 H 2) reacts with an equimolar amount of sulfur to yield the first thioxo-A 5 -diphosphenyl com-plex (/7 5 -C 5 Me 5)(CO) 2 Fe-P(= S) = P-Ar (2). Heating of 2 in boiling benzene affords the metal functionalized thiadiphosphirane 3. Similarily the selenoxo-A 5 -diphosphenyl complex (^ 5 -C 5 Me 5)(CO) 2 Fe —P(=Se) = P—Ar (5) and selena-diphosphirane 6 are synthesized. The prod-ucts have been characterized by elemental analysis as well as by spectroscopic data (IR, 'H, 13 C, 31 P NMR, MS). The molecular structure of 2 has been elucidated by single crystal X-ray analysis.

 Title    T etramethylcyclopentadienylindium(I) und Tetramethylcyclopentadienylthallium(I): Synthese, Charakterisierung und Röntgenstrukturanalyse Tetramethylcyclopentadienylindium(I) and Tetramethylcyclopentadienylthallium(I): Synthesis, C haracterization and X-Ray Structural Analysis  
 Abstract    Tetramethylcyclopentadienyllithium was reacted with InCl to form [C5H M e4]In (1). [C5H M e4]Tl (2) was prepared from tetramethylcyclopentadiene and T10C2H 5. The 'H and 13C N M R spectra o f the new com pounds as well as the X-ray crystal structures of the polymeric metallocenes 1 and 2 are reported and discussed in relation to the structures o f other cyclo-pentadienylindium(I) and -thallium(I) compounds.
