Hi

I have to discover the reagents (= which type of reactions are)fort these reactions:



For the first one I think it's the Mizoroki-Heck reaction

For the second the first step I think is also a Mizoroki-Heck ...but the second step I don't understand the reagents used

I see that Bromine is the leavong gropup and I have an aromatic ring
So I have perhaps a nucleophilic substitution...but I don't know how to  create the nucleophile


Thanks

I'm not sure if those reaction are Heck reaction...
I would like to have a confirmarion.

Also I've tried a mechanism for tuecsecond step of the second reaction:


Could it be right?
PS: the title question is a bit wrong...I would like to know which type of reaction are
Thanks
