 Her methods led to her synthesis of fatty acids with the greatest molecular weights of the time (specifically, tricontanoic and 13-oxodotetracontanoic acids).She also independently suggested the asymmetric structure of aromatic azoxy-compounds and, with her husband, postulated a mechanism for the Fischer Indole Synthesis.Based on this mechanism and working off the pyrrole syntheses of Piloty, the couple provided a method for synthesizing tetraphenylpyrrole .
