Abstract
[2-(Me2NCH2)C6H4]Se-S(S)PR2 [R = Ph (1), (OPr)-Pr-i (2)] were prepared by reacting [2-(Me2NCH2)C6H4](2)Se-2 with the appropriate disulfanes, [R2P(S)S](2). The compounds were characterized by multinuclear magnetic resonance (H-1, C-13, P-31). The molecular structures of 1 and 2 were determined by single-crystal X-ray diffraction. Both compounds are monomeric and the nitrogen atom of the pendent CH2NMe2 arm is strongly coordinated to the selenium atom. The organophosphorus ligands are monodentate, thus resulting in a T-shaped coordination geometry around selenium.
