Could you give examples of f \in L^2(R) - L^1(R) such that the fourier
transform of f is in L^1(R). Under what circumstances can this happen ?

Try sin(x)/x. This is always the case when f is the
Fourier transform of a discontinuous L^1 function,
as the Fourier transform of an L^1 function is continuous.
