Have you heard of a Kumada coupling? That'll do it, I think. You might also look up the Corey-House and the Wurtz reactions. There are other ways, but they would take a couple of steps. If none of the name reactions I mentioned mean anything to you, then you are probably going to have to do it in a more stepwise fashion.
The second one can be done with a Grignard. What would you want to quench the t-butyl Grignard reagent with?
