Novel multitopic diphos-type ligands


Kunz, P C; Wetzel, C; Bongartz, M; Noffke, A L; Spingler, B (2010). Novel multitopic diphos-type ligands. Journal of Organometallic Chemistry, 695(15-16):1891-1897.

Abstract

Seven novel imidazole and thiazole derivatives of diphos-type ligands are presented. They are of the general structure R2P(CH2)(2)PR2, where R is imidazol-2-yl (1), 1-methylimidazol-2-yl (2), 1-methyl-benzimidazol-2-yl (3), 1-methylimidazol-5-yl (4), 2-isopropylimidazol-4(5)-yl (5), thiazol-2-yl (6), benzothiazol-2-yl (7), thiazol-4-yl (8) or thiazol-5-yl (9). Syntheses involved direct metallation or halogen-metal exchange reactions. Their solubility, especially in aqueous solution, is strongly dependent on the nature of the substituents as is their partition coefficient log D. The crystal structures of compounds 2, 3, 7a and 9 as well as the structure of the rhodium complex (2)(2)Rh2Cl2]Cl-2 (10) have been determined. (C) 2010 Elsevier B. V. All rights reserved.
