Abstract
We call a CW-complex unstable, if all attaching maps vanish under suspension. For a one-connected CW-space X we construct a unstable CW-complex ¯X and a mapping ¯X→X, which is a rational homotopy equivalence. As an application we imbed the rational Hurewicz-homomorphism into an exact sequence.
