Synthesis and structures of aryloxo- and binaphthoxogermanium(IV) alkyl iodide complexes
摘要:
The germanium(II) aryloxide complexes (S)-[Ge{O2C20H10-(SiMe2Ph)(2)-3,3'}{NH3}] (1) and [Ge(OC6H3Ph2-2,6)(2)] (2) react with either (BuI)-I-t or MeI to yield the corresponding germanium(IV) compounds (S)-[Ge{O2C20H10-(SiMe2Ph)(2)-3,3'}{Bu-t}{I}] (3), (S)-[Ge{O2C20H10-(SiMe2Ph)(2)-3,3'}{Me}{I}] (4), [Ge(OC6H3Ph2-2,6)(2)(Bu-t)(I)] (5), and [Ge(OC6H3Ph2-2,6)(2)(Me)(I)] (6). Compound 6 reacts with 2,6-diphenylphenol to yield [Ge(OC6H3Ph2-2,6)(3)(Me)] (7), while 3-5 do not. The X-ray crystal structures of 3-5 and 7 were determined, and 3-5 represent the first structurally characterized germanium(IV) species having germanium bound to both oxygen and iodine.
