Presented herein is a general protocol for the alkylation of simple aryl fluorides with unbiased secondary Grignard reagents by means of nickel catalysis. This study revealed a general Thorpe–Ingold effect in the ligand backbone which confers a high degree of selectivity for the secondary carbon center in the C?C coupling event. This protocol is characterized by mild reaction conditions, robustness, and simplicity. Both electron-rich and electron-deficient aryl fluorides are suitable candidates in this transformation. Equally amenable are a variety of heterocycles, permitting the coupling without over alkylation at the electrophilic sites.

trans-1,3-Dithiane 1,3-dioxide, prepared by stereoselective oxidation of 1,3-dithiane has been found to be thermodynamically more stable than the cis-isomer by equilibration studies using N2O4 and has been found to undergo highly selective (20:1) aldol ty
