Using a data sample collected with the BESIII detector operating at the BEPCII storage ring at a centerof- mass energy of √s = 4.600 GeV, we search for the production of e+e- φχc0,1,2. A search is also performed for the charmonium-like state X(4140) in the radiative transition e+e- γX(4140) with X(4140) subsequently decaying into φJ/ψ. The processes e+e- φχc1 and φχc2 are observed for the first time, each with a statistical significance ofmore than 10σ, and the Born cross sections are measured to be (4.2+1.7 -1.0±0.3) pb and (6.7+3.4 -1.7 ± 0.5) pb, respectively, where the first uncertainties are statistical and the second systematic. No significant signals are observed for e+e- φχc0 and e+e- γX(4140) and upper limits on the Born cross sections at 90% confidence level are provided at √s = 4.600 GeV.
