摘要：

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: D = 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 H-1, C-13 and Se-77 n.m.r. spectra.
