Synthesis and Characterization of N,N'-Bismesityl Phenanthrene-9,10-diimine and Imine-Nitrone.

ABSTRACT: The sterically bulky compounds N,N'-bismesityl phenanthrene-9,10-diimine [1] and imine-nitrone [2] were synthesized. To the best of our knowledge, this is the first report of the synthesis of a bulky steric imine-nitrone accessed from the secondary ketimine using urea hydrogen peroxide over methyltrioxorhenium catalyst. Purified compounds were characterized using ¹H and ¹³C NMR, high-resolution mass spectrometry, and infrared spectrometry. We report the first crystal structure of compound 1. Detailed IR bands of compounds 1 and 2 were assigned by comparing experimentally measured spectra to individually animated modes of quantum mechanically computed spectra. We believe these compounds may be of use as bidentate ligands
