What would be the major organic product of the following Heck reaction?

Question

Quizplus · Accepted Answer

The major product of the Heck reaction involves the coupling of an aryl or vinyl halide with an alkene in the presence of a palladium catalyst. In this reaction, compound III is the aryl halide and compound II is the alkene. The reaction proceeds through the formation of a palladium intermediate which undergoes beta-hydride elimination to give the final product. The product is compound I, which is the product of the aryl and alkene coupling. Therefore, the correct answer is C.
