Experiments with the CMD-3 detector at the VEPP-2000 electron-positron collider in the range of center of mass collision energies from 0.32 to 2 GeV have been performed since December 2010. The amount of accumulated data corresponds to an integrated luminosity of about 60 pb. The resultsof a preliminary analysis are presented for the following annihilation channels: e e → 3(ππ), 2(πππ), K Kππ, K K, $$p\bar p$$, and ππ. Since processes of electron-positron annihilation that involve the production of multihadron states proceed through several intermediate states, their analysis is necessary for the correct description of the emission-angle and invariant-mass distributions of product particles.
