Özet
Silica-supported catalytically active functional materials, such as the rhodium(I) carbene complex with 1-(triethoxysilylpropyl)-3-(2,4,6-trimethylbenzyl)imidazolidine-2-ylidine (L), were prepared using the sol–gel method. The complex (1; COD = 1,5-cyclooctadiene) RhCl(COD)[1-(triethoxysilylpropyl)-3-(2,4,6-trimethylbenzyl)imidazolidin-2-ylidine] was characterized by conventional spectroscopic methods and elemental analyses and the silica-supported functional material RhCl(COD)(L) were tested for the catalytic addition of phenylboronic acid to aldehydes.
