Stability. -This is the first transition metal-catalyzed Suzuki--Miyaura coupling reaction between a tertiary alkyl halide and a wide variety of aromatic boronic acids. The process probably involves the formation of a radical species which is prevented from cis-trans-isomerization due to the silylene structure. The use of tert-butanol as reaction medium is crucial, because of its stability under radical--generating conditions. - (YOTSUJI, K.; HOSHIYA, N.; KOBAYASHI, T.; FUKUDA, H.; ABE, H.; ARISAWA*, M.; SHUTO, S.; Adv.
