Synthesis and Characterization of an Amidinate-Stabilized Bisgermylene Oxide and Sulfide
摘要:
The synthesis and characterization of the amidinate-stabilized bisgermylene oxide and sulfide [(LGe)-Ge-2-E-GeL2] (E = 0 (2), S (3); L-2 = (BuC)-C-t(NAr)(2), Ar = 2,6-(Pr2C6H3)-C-i) 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 [(LGe1)-Ge-2] 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 THE afforded 3. Compounds 2 and 3 have been characterized by NMR spectroscopy and X-ray crystallography.
