    Description / Table of Contents: Summary We present the fourth case report of an extraovarian Brenner tumor, which was an incidental finding in a total hysterectomy 53-year-old woman. The morphology and pathogenesis of Brenner tumors are discussed.
    Notes: Zusammenfassung Es wird über den vierten Fall eines solchen Tumors in der Weltliteratur berichtet, der bei einer 53 Jahre alten Frau im Rahmen einer totalen Hysterektomie als Zufallsbefund erhoben wurde. Die Morphologie und Pathogenese der extraovariellen Brenner-Tumoren werden diskutiert.

    Description / Table of Contents: Tris(trimethylsilyl)methaneselenenyl Halides and Chalcogenides.Ditrisyldiselenide (1) (trisyl = TSi = (Me3Si)3C) reacts with SOCl2, Br2 and I2 to provide trisylselenenyl halides TSiSeX (2: X = Cl; 3: X = Br, 4: X = I). Insertion of S and Se into the Se—Se bond of 1 to yield (TSiSe)2Sn (5: n = 1; 6: n = 2) and (TSiSe)2Sen (7: n = 1; 8: n = 2) was catalysed by iodine. 5 was isolated in pure state and examined by X-ray diffraction. Triselenide 7 can be cleaved by I2 in CS2 to give 4 and Se2I2 (9). From 2 with Me3SiCN and Me3SiNCS, the new selenenyl pseudohalides TSiSeCN (10) and TSiSeSCN (11) were prepared. The compounds were characterised by 1H, 13C- and 77Se n.m.r. spectra.
    Notes: Ditrisyldiselenid (1) (Trisyl  -  Tsi  -  (Me3Si)3C—) reagiert mit SOCl2, Br2 und I2 zu Trisylselenenylhalogeniden TSiSeX (2: X = Cl; 3: X = Br, 4: X = I). Die Einschiebung von Schwefel und Selen in die Se—Se-Bindung von 1 zu (TSiSe)2 Sn (5: n = 1; 6: n = 2) bzw. (TSiSe)2Sen (7: n = 1; 8: n = 2) läßt sich mit Iod katalysieren. 5 wurde in reiner Form isoliert und durch Röntgenstrukturanalyse untersucht. Das Triselenid 7 wird durch Iod in CS2 zu 4 und Se2I2 (9) gespalten. Aus 2 lassen sich mit Me3SiCN bzw. Me3SiNCS das Trisylselenocyanat TSiSeCN (10) bzw. Trisylselenenylthiocyanat TSiSeSCN (11) gewinnen. 1H, 13C- und 77Se-NMR Spektren von 1 - 11 sind im Einklang mit den Strukturvorschlägen.
