congested quaternary centers is highly sought-after. Herein, we report a method for the cross-coupling of C(sp3) tertiary Grignard reagents with C(sp2) styrenyl bromides using readily available nickel precatalysts. We identified conditions that afford the products in practical yield for several combinations of electrophiles and nucleophiles, including sensitive α-magnesiated Grignard reagents. Dependent
