(Chemical Equation Presented) Control through molecular pockets: Calixarene-derived diphosphites provide effective hemispherical crowding about catalytic centers. When used in the palladium-catalyzed alkylation of cinnamyl acetate, regioselectivities higher than 98% in favor of the linear product are observed. In the rhodium-catalyzed hydroformylation of styrene, these diphosphites lead to phenylpropionaldehyde with selectivities as high as 76%.
