Abstract

The reaction of 1-naphthylamine with one equivalent of chlorodiphenylphosphine in the presence of triethylamine gave the (1-NHC 10H 7)PPh 2 (1) ligand. Refluxing of 1 with elemental sulfur or grey selenium in toluene (1:1 molar ratio) afforded (1-NHC 10H 7)P(S)Ph 2 (2) and (1-NHC 10H 7)P(Se)Ph 2 (3), respectively. Moreover, the byproduct {Ph 2P(S)} 2O (4) was isolated from the reaction of 1 with elemental sulfur. Compounds 1-3 were identified and characterized by multinuclear ( 1H, 13C, 31P, 77Se) NMR spectroscopy, mass spectrometry, and elemental analysis. Crystal structure determinations of 3 and 4 were carried out. Copyright © 2012 Taylor and Francis Group, LLC.
