Gm. Li et al., SYNTHESIS AND STRUCTURE OF TELLUROAMIDES AND SELENOAMIDES - THE FIRSTCRYSTALLOGRAPHIC STUDY OF TELLUROAMIDES, Organometallics, 16(4), 1997, pp. 756-762
The reaction between bis(trialkyltin) chalcogenides and trimethylalumi
num results in the formation of bis(dimethylaluminum) chalcogenides, (
Me(2)Al)(2)E, where E is S, Se, or Te. Reaction between the latter and
carbonyl groups (but not carboxylic acids or eaters) converts them to
carbon-chalcogen double-bond (C=E) compounds. Using this procedure, w
e have successfully synthesized several telluro- and selenocarbonyl co
mpounds. The first successful synthesis of an isolable, crystalline te
lluroformamide, 4-(telluroformyl)morpholine (3c, C5H9-NOTe), and its c
rystal structure are reported. Also, the syntheses and crystal structu
res of a gamma-tellurolactam, 1-methyl-2-telluroxopyrroline (3d, C5H9N
Te), and two selenoamides, N,N-diphenylselenoformamide (3a, C13H11NSe)
and N-methyl-N-(4-nitrophenyl) selenoformamide (3b, C8H8N2O2Se) are d
escribed.
