文摘

Bis[(2-pyridyl)bis(trimethylsilyl)methyl-C,N]germanium(II)(1) reacts with elemental chalcogens (sulfur, selenium, tellurium) to give the corresponding thione(2), selenone (3), andtellurone (4) at room temperature. At elevatedtemperatures, the dihydropyridinatocompounds 5 and 6 are formed by a1,3-trimethylsilyl shift from one of the methyl bridgesto the sulfur and selenium atoms in 2 and 3,respectively. The compounds were characterizedby NMR spectroscopy (¹H, ¹³C,²⁹Si, ⁷⁷Se, ¹²⁵Te),MS (EI), and elemental analysis. X-raycrystal structure determinations are presented for 1,3, 4, and 5.
