Applications of integrand reduction to two-loop five-point scattering amplitudes in QCD

We review the current state-of-the-art in integrand level reduction for five-point scattering amplitudes at two loops in QCD. We present some benchmark results for the evaluation of the leading colour two-loop five-gluon amploitudes in the physical region as well as the partonic channels for two quarks and three gluons and four quarks and one gluon.
