Question

High-valency gold complexes with this geometry have been catalyst candidates for enantioselective cyclizations. Ligand substitutions of complexes with this geometry form intermediates that undergo Berry pseudorotation. (10[1]-5[7])An addition (-5[2])of methyl (-5[1])iodide (-5[1])to an iridium complex with this geometry (10[1])is the first step in the (-5[1])Cativa process. Low-spin d8 complexes, which have this (-5[1])geometry, violate the 18-electron rule, (10[1])as exemplified by group 10 complexes such as Zeise’s salt. Compounds (10[1])with this geometry have D4h point groups. Complexes with this geometry are (10[1])stabilized by (-5[1])the “trans effect,” which impacts the synthesis of (10[1])cisplatin, (10[1])a drug with this geometry. (-5[1])For (10[1])10 (-5[1])points, (10[1])name this geometry of compounds that have (10[1])four substituents (-5[2])and two lone (10[1])pairs, (10[1])in which all bond angles are (10[1])90 degrees. (10[2])■END■ (10[7]0[10])
