The specific rotation of (RFe,R,M)-4 switches sign upon epimerisation to (RFe,S,P)-5. X-Ray crystallographic studies suggest that inversion of the propeller configuration of the coordinated PPh3 ligand is the major contributor to the switch of specif...

A variety of α-hydroxy carboxylic acid salts [AgO2CC(OH)R1R2] react with SbPh3Cl2 1 to afford the cyclometalled complexes 4b-g. A single crystal X-ray analysis of (±)-4g reveals the presence of conformational diastereoisomers arising from the helical...
