AgSbF6-controlled diastereodivergent hydroarylation reactions were developed. Unprecedented and remarkable switching of the E/Z-stereoselectivity could be obtained by adjusting the AgSbF6 loading.
rhodium-catalyzed ortho-alkenylation of phenyl sulfoxides using alkenes or alkynes as substituent sources proceeds efficiently through sulfoxide group directed C–H bond cleavage to produce the corresponding o-alkenylphenyl sulfoxides. The products readily undergo interrupted Pumerer cyclization as well as reduction to afford benzothiophenes and o-alkenylphenyl sulfides.
