  This article reviews recent progress in formulating double-copy constructions
for scattering amplitudes in supergravity theories with N=2 supersymmetry in
five and four spacetime dimensions. Particular attention is devoted to infinite
families of Maxwell-Einstein theories with symmetric and homogeneous target
spaces and to Yang-Mills-Einstein theories with compact gauge groups. Extension
of the construction to theories with spontaneously-broken gauge symmetry is
also discussed.
