WebThe reduction of trans-CrCl 2 (dmpe) 2 [dmpe = 1,2-bis(dimethylphosphino)ethane] in tetrahydrofuran by sodium amalgam under dinitrogen leads to the complex trans-Cr(N 2) 2 (dmpe) 2, under carbon monoxide to the known cis-Cr(CO) 2 (dmpe) 2, and in presence of Bu t NC to trans-Cr(CNBu t) 2 (dmpe) 2. WebLike the Re analogue, the ligand-to-metal charge transfer (LMCT) excited-state of [Tc(dmpe)3]2+ (dmpe is bis-1,2-(dimethylphosphino)ethane) is luminescent in solution at room temperature. Surprisingly, both [M(dmpe)3]2+* species have extremely large excited-state potentials (ESPs) as oxidants-the highest for any simple coordination complex of a … greg norman performance golf shorts
