Concept introduction:
The Heck Mizoroki reaction is a coupling reaction between an alkene and an alkenyl or aryl halide in the presence of a palladium catalyst and a base, usually an
Ring closing metathesis is a process in
Stille coupling is a reaction in which organotin compounds are coupled with organic halides. Here, organotin compounds are used as coupling agents. This reaction takes place in the presence of palladium catalysts.

- Use line structures and write the mechanism for the first and second steps of the hydrobromination reaction of compound C in the presence of HBr to demonstrate that it is a regioselective reaction. Clearly indicate the following: a) the flow electrons in step 1 and in step 2 and b) draw the product D(product 2) resulting from step 2. Include stereo chemistry in your answer.arrow_forwardEach of the following reactions has been reported in the chemical literature and proceeds in good yield. What are the principal organic products of each reaction? In some of the exercises more than one diastereomer may be possible, but one of them is either the major product or the only product. For those reactions in which one diastereomer is formed preferentially, indicate its expected stereochemistry.arrow_forwardProvide the suitable reagents to effect the following transformations. I specifically need help on sub-parts d, e, f, g, h, and i.arrow_forward
