You have to make it.  Your question is too non-descript to answer the rest.

The first bit has been answered by J - bone.
I'll guess what you meant in second the question.
lithium dialkyl cuprate is good for conjugate addition reaction while Grignard or alkyllithium is good for direct addition at carbonyl.

Cheers.
