Bidentate pyrrolyl lithium complexes: Synthesis, crystal structure and catalytic activity for the cyclotrimerization of isocyanates
摘要:
Three bidentate pyrrolyl lithium complexes were synthesized and their application for the cyclotrimerization of isocyanate to corresponding isocyanurate has been investigated and show high catalytic activities. All lithium complexes were characterized by NMR spectroscopy, elemental analysis and X-ray diffraction analysis. (C) 2013 Elsevier B.V. All rights reserved.
