There have been a lot of research about the structure of finite solvable groups G admitting a Frobenius group FH of automorphisms such that the Frobenius-kernel F acts fixed-point-freely on G, finding relations between some group-theoretic invariants of G and the corresponding invariants of the fixed-point-subgroup of H in G, like nilpotent length, rank, order, derived length. In this talk some generalizations of these results will be discussed and some recent results of Ercan,Güloğlu and Khukhro, obtained by replacing Frobenius groups by the so-called "Frobenius-like groups" will be presented. These are groups containing a nontrivial, nilpotent normal subgroup F with a nontrivial complement H so that [F,h]=F for any nonidentity element h of H.
