In spring 2009 BES III has taken its first large data sample on the {psi}(2S) resonance. More than 1{center_dot}10{sup 8} {psi}(2S) decays have been recorded. First results on the analyses {chi}{sub cJ{yields}{pi}}{sup 0{pi}0}, {chi}{sub cj{yields}{eta}{eta}} and {chi}{sub cj{yields}{phi}{phi}} are presented. The decay mode {chi}{sub c1{yields}{phi}{phi}} has been observed for the first time. The results presented in this document are preliminary.
