## Abstract New mononuclear titanium complexes [TiCl(Rcalix)] [R = Me (1), Bz (2), SiMe~3~ (3)] supported by __p__β__tert__βbutylcalix[4]arene mono(organyl)ethers (Rcalix) were prepared in good yield from H~2~R~2~calix and [TiCl~4~(THF)~2~]. The crystallographically characterized complex [TiCl(Meca
The hetero-armedp-(tert -butyl)calix[4]arene 1 was synthesized by a stepwise procedure. This ligand presented a very strong complexing behavior towards Cu', giving the chiral complex 2 and parent species when reacted with Cu" salts. High-resolution NMR techniques were employed for the characterizati
