                      Here we show the influence of different dispersion times
                      before microwave-induced decomposition of the precursors on
                      the phase purity, as well as the influence of the time of
                      microwave-induced decomposition on the crystallinity of the
                      NiGa nanoparticles. Microwave-induced co-decomposition of
                      all-hydrocarbon precursors [Ni(COD)2] (COD =
                      1,5-cyclooctadiene) and GaCp* (Cp* =
                      pentamethylcyclopentadienyl) in the ionic liquid
                      [BMIm][NTf2] selectively yields small intermetallic Ni/Ga
                      nanocrystals of 5 ± 1 nm as derived from transmission
                      electron microscopy (TEM) and high-angle annular dark-field
                      scanning transmission electron microscopy (HAADF-STEM) and

                      selectivity towards (E)-4-octene over five runs, but with
                      poor conversion values. IL-free, precipitated NiGa
                      nanoparticles achieve conversion values of over $90\%$ and
