  We consider the momentum-space 3-point correlators of currents, stress
tensors and marginal scalar operators in general odd-dimensional conformal
field theories. We show that the flat space limit of these correlators is
spanned by gauge and gravitational scattering amplitudes in one higher
dimension which are related by a double copy. Moreover, we recast
three-dimensional CFT correlators in terms of tree-level Feynman diagrams
without energy conservation, suggesting double copy structure beyond the flat
space limit.
