Treatment of group 14 metal dialkyl MRN2 (M = Ge or Sn) with elemental chalcogens (sulfur, selenium, or tellurium) in THF afforded the corresponding chalcogenones RN2M=E [RN = CPh(SiMe3)C5H4N-2; M = Ge; E =S (4), Se (5), Te (6); M = Sn; E = S (7), Se (8); RN = CH(SiMe3)C9H6N-8, M = Sn; E = Se (10), Te (11)]. In contrast, a sulfido-bridged dimer [RN2Sn(μ-S)]2 (9) was obtained from similar reaction of SnRN2 [RN = CH(SiMe3)C9H6N-8] with elemental sulfur. These chalcogenones have been characterized by elemental analysis, 1H, 13C, 119Sn, 77Se, and 125Te NMR, and mass spectroscopy, X-ray structure of 5, 8, 9, 10, and 11 have been determined. It was revealed that compounds 5, 8, 10, and 11 consist of a terminal metal-chalcogen bond with the ligands RN acting in a C,N-chelate fashion, except for 9, which is a sulfido-bridged dimer.
