Sterically Rigid Unsymmetrical Acenapthenene Imine (Ar-BIAN) Ligands in Zinc Coordination Sphere – Synthesis and Structures.
Masters thesis, Indian Institute of Technology Hyderabad.
Abstract
First part of my M.Sc. thesis I have described the synthesis of (Dipp-BIAN-silyl) i.e. N-2-((2,6-
diisopropyl)imino)acenaphthylen-1(2H)-ylidene)-1,1,1-trimethylsilanamine ligand (1a), which
was prepared from reaction of corresponding Ar-BIAO ligands with lithiumbis(
trimethylsilanamine) (LiN(Si(CH3)3)2) and stir at 50 ᵒC for 11/2 h, then cooled at room
temperature, and followed by Me3SiCl in toluene under reflux at 80 °C. The ligand N-(2-
iminoacenaphthylen-1(2H)-ylidene)-2,6-diisopropylaniline (Ar-BIAN-H) (1b) was obtained from
desilylation of ligand 1a under reflux condition in methanol at 50 ᵒC for 2-3 h. The synthesized
ligands 1a and 1b were characterized by FT-IR, UV-visible, 1H, 13C {1H} NMR spectroscopy. The
solid state structures of compounds 1a and 1b were established by single crystal X-ray diffraction
analysis.
