Coupling an aryl tin reagent with an alkenyl halide,using a Pd catalyst,is an example of ____.
A)Stille Coupling
B)Suzuki-Miyaura Coupling
C)Heck-Mizoroki Coupling
D)Sonogashira Coupling
E)Gilman Reagent-Mediated Coupling

Question

Quizplus · Accepted Answer

The Stille coupling involves the coupling of an organotin compound with an organic halide using a palladium catalyst. In this case, the aryl tin reagent and alkenyl halide would be coupled using a Pd catalyst, making it an example of Stille coupling. Suzuki-Miyaura coupling typically involves the coupling of an organoboron compound with an organic halide, while Heck-Mizoroki coupling involves the coupling of an aryl or vinyl halide with an alkene, and Sonogashira coupling involves the coupling of an aryl or vinyl halide with a terminal alkyne. The Gilman reagent-mediated coupling involves the use of organocopper reagents and is not described in the question stem.
