The tighter, the better! Fluorobis(phenylsulfonyl)methane reacts readily with aldehydes to give addition products in excellent yields (see scheme; LiHMDS=lithium hexamethyldisilazide), which is in sharp contrast to previous findings. Both strongLi–Ocoordination at low temperature and fluorinesubstitution play important roles in successful CCbondformation.
