trans‐2‐Arylcycloalcohol derivatives are obtained in high diastereoselectivity by the iron‐mediated cross‐coupling of cyclic TBS‐protected iodohydrines with aryl Grignard reagents (see scheme; TBS=tert‐butyldimethylsilyl). The stereoconvergent cross‐coupling of a chiral TBS‐protected 2‐iodocyclohexanol provides the 2‐arylcyclohexanols with no loss of stereochemical purity, and is a valuable alternative
