Original Title:
Σύνθεση, χαρακτηρισμός & μελέτη της καταλυτικής δραστικότητας των συμπλόκων [Μ{Ph2P)2N(CH2)3Si(OCH3)3-P,P?}I2], M = Ni, Pd, σε αντιδράσεις σύζευξης Suzuki
Summary:
In this study, the synthesis and spectroscopic characterization of complex
compounds of the type [Μ{Ph2P)2N(CH2)3Si(OCH3)3-PP’}I2] M=Ni,Pd, has been
accomplished. The three-dimensional structure of the two complexes was
determined by X-ray crystallography. The PdII complex was immobilized on
montmorillonite (clay type), via the SiOR3 moiety of the coordinated ligand.
The catalytic activity of both the free and the immobilized PdII complex in
Suzuki coupling reactions was evaluated. The data obtained reveal some profound
advantages in using the immobilized PdII catalyst over the free PdII complex,
such as a higher product yield in the coupling reactions investigated.
