The calculation of two-loop Feynman integrals within the dimensional regularization scheme requires the knowledge of scalar one-loop integrals up to the linear term inD-4. We give the corresponding explicit expressions in terms of polylogarithms for the general one-, two-and three-point function and for a special case of the fourpoint function needed for vertex corrections. Our results are valid in all kinematical regions for real masses and momenta.
