Synthese und Röntgenstrukturanalyse luftstabiler Bis[3-(dimethylamino)propyl]indium-Derivate

Synthesis and X-ray Structural Analysis of Airstable Bis[3-(dimethylamino)propyl]indium Derivatives Pentacoordinate, intramolecularly base-stabilized organoindium compounds [Me2N(CH2)3]2InBr (1), [Me2N(CH2)3]2InO2-CCF3 (2) and [Me2N(CH2)3]2InOC6F5 (3) as well as [Me2N-(CH2)3]2InC2H5 (4), [Me2N(CH2)3]2In(i-C3H7) (5), and [Me2N-(CH2)3]2In(t-C4H9) (6) have been prepared by the reaction of indium tribromide with 3-(dimethylamino)propyllithium and of bis[3-(dimethylamino)propyl]indium chloride with NaO2C-CF3, LiOC6F5, C2H5MgBr, i-C3H7MgBr, and t-C4H9Li, respectively. The 1H-, 13C-, 19F-NMR and mass spectra of the new compounds as well as the single-crystal X-ray structure analysis of 1 are described and discussed.
