Synthesis and characterization of sterically hindered arylsilanes containing the 2,4,6-trimethoxyphenyl ligand (TMP): X-ray structures of (TMP)SiH3, (TMP)2SiH2, and (TMP)3SiH
摘要:
The homologous series of primary, secondary and tertiary silanes containing the sterically demanding 2,4,6-trimethoxyphenyl (TMP) group have been prepared in yields ranging from 22 to 45%. The arylsilanes were characterized by multinuclear NMR, IR, GC-MS, elemental analyses, and X-ray crystallography. Relatively short intramolecular distances are observed between Si and the O atoms in the ortho-methoxy groups of the aryl ligand and are shorter than the sum of the van der Waal's radii in the solid state for all three arylsilanes.
