Abstract :
[en] Novel eight-membered ring unsaturated lactams were synthesized and tested as monomers for the ruthenium-catalyzed ring-opening metathesis polymerization (ROMP). The reaction of a N-protected cyclic alkeneamine was also investigated. The Grubbs' benzylidene complexes RuCl2(=CHPh)(PCy3)(2) or RUCl2(=CHPh)(PCy3)(IMesH(2)) and selected ruthenium-arene species bearing either phosphine or stable Arduengo-type N-heterocyclic carbene ligands served as catalyst precursors. In most cases, isomerization of the starting materials took place and only 1-benzyl-1-aza-2-ketocyclooct-5-ene afforded a polymeric product. This polyamide was characterized by numerous analytical techniques. (C) 2002 Elsevier Science B.V All rights reserved.
