Novel ferrocenyl-oxazoline ligands: first preparation of non-symmetrical bis(oxazoline)
摘要:
New ferrocenyl-arenylethenyl-oxazoline derivatives have been prepared (5-10) from the mono- and (1,1')-disubstituted (nitrile-ethenylaryl)ferrocene compounds (1 and 2) and the appropriated beta-aminoalcohol (3 and 4) in one step synthesis. The X-ray crystal structure of one of the ferrocenyl-ethenylaryl-oxazoline (5) is described, revealing the unusual quasi-planarity of the oxazoline ring with the phenyl and cyclopentadienyl cycles. Two compounds end-capped (9 and 10) with both, nitrile and oxazoline groups, are the key intermediates to obtain the non-symmetrical bis(oxazoline) 11, containing two different substituted heterocycles.

Synthesis and characterization of new ferrocenyl heterobimetallic compounds with high NLO responses
摘要:
Several ferrocenyl based heterobimetallic compounds have been obtained and characterized, and their NLO responses have been measured. We find that the observed beta values are among the highest of the organometallic based materials reported up to date. (C) 1998 Elsevier Science S.A. All rights reserved.
