Publikováno v: Helvetica Chimica Acta, 84(10), 3269-3280. Wiley-Blackwell

The novel bulky diphosphite (P∩P) ligands (3 and 4) based on the 2,7,9,9-tetramethyl-9H-xanthene-4,5-diol (2) backbone were investigated in the Rh-catalyzed hydroformylation of oct-1-ene, styrene, and (E)-oct-2-ene. These diphosphites gave rise to

Coordination Chemistry of Calix-Phosphanes: Cooperativity in the Assembly of a Tetragold Calixarene Complex

Autor: Cedric B. Dieleman, Dominique Matt, Anthony Harriman

Publikováno v: European Journal of Inorganic Chemistry. 2000:831-834

Assemblage of the tetragold complex [L·(AuCl)4] from p-tert-butyl-calix[4]-(OCH2PPh2)4 (L) and [AuCl(tetrahydrothiophene)] was investigated by NMR and UV/Visible spectroscopic titrations. Three steps could be resolved and are assigned, respectively,
