Dipodal ligands from chiral spiro[2.4]hepta-4,6-dienes: solid state conformational effects by tether substitution in dipodal η5,η1-CpP–ruthenium(II) complexes
摘要:
New chiral spiro[2.4]hepta-4,6-dienes were prepared and used in an efficient synthesis of cyclopentadienyl ruthenium complexes with pendant phosphine donors. Solid state structures reveal a conformation trend among three structurally homologous complexes that involves subtle twisting about the tether with increasing substitution at the alpha carbon. These results suggest architectural requirements for future ligand designs. (C) 2003 Elsevier Science Ltd. All rights reserved.
