Synthesis and characterization of β-diketiminate germanium(II) and tin(II) bromides
摘要:
The equimolar reaction of a beta-diketiminate lithium salt LLi(OEt2) [L = HC(CMeNAr)(2); Ar = 2,6-iPr(2)C(6)H(3)] with either GeBr2 or SnBr2 in diethyl ether affords the synthetically useful monomeric beta-diketiminate-element halides LGeBr (1) and LSnBr (2), respectively. Both are soluble in hydrocarbon solvents, stable in inert atmosphere, and have been characterized by elemental analysis, NMR spectroscopy, and single-crystal X-ray diffraction analysis.
