For the German law feel free to read my statement in German at
It depends from the contract if a publisher has exclusive rights which
forbidd the author to publish another version.
D and F are the same work and have the same copyright (because the
derivative work D of F or F of D - the chronology isn't relevant - is
NOT a "free" derivative use = "Freie Bearbeitung").
But concerning contractual law I have serious doubts that publishers
get such exclusive rights according German law.
