This question was brought up in the problem session today. From what
I understood from the discussion the use of organolithium reagents
should produces the same results as a Corey-Posner, Whitesides-House
synthesis, essentially the formation of a C-C bond. So I believe the
answer to your first question is yes. However, according to Dr.Fryhle,
the C-P, W-H synthesis is a difficult reaction to carry out. So though it
is a useful reaction, it is easier to use an organolithium. Furthermore,
since Mg is more reactive than Li and Grignard reagents are easier to
prepare than organolithium reagents, a Grignard reaction is the best way
to synthesize a C-C bond formation.
Hope this helps.
