Synthesis and Characterization of an Amidinate-Stabilized Bisgermylene Oxide and Sulfide

The synthesis and characterization of the amidinate-stabilized bisgermylene oxide and sulfide [L2Ge−E−GeL2] (E = O (2), S (3); L2 = ButC(NAr)2, Ar = 2,6-Pri2C6H3) are described. Compound 2 was prepared by the reaction of two equivalents of [L2GeCl] (1) with Me3NO and two equivalents of KC8 in THF. It is proposed that the reaction proceeds through an [L2GeI] intermediate, which then reacts with Me3NO to form 2. Similarly, the reaction of two equivalents of 1 with elemental sulfur and two equivalents of KC8 in THF afforded 3. Compounds 2 and 3 have been characterized by NMR spectroscopy and X-ray crystallography.
