Synthesis of 4-(2-Indenylethyl)morpholine and their cationic transition metal complexes

摘要

The amido tethered ligand 4–(2–indenylethyl)morpholine (6) have been prepared in high yield (71%). All the compounds were fully characterized by NMR, IR, Mass Spec. and Microanalysis. Treatment of the lithio salt of (6) with TiCl4:2THF in THF afforded the new complex 4–(2–indenylethyl)morpholinetitanium dichloride (7a) in 26% yield as viscous green oil while, treatment with ZrCl22THF gave 4–(2–indenylethyl)morpholinezirconium dichloride (7b) in 63% yield as yellow solid. The new compounds (7a and 7b) were characterized by Mass Spectroscopy and Micro Analysis.
