Abstract: Using a data sample of $448.1\ifmmode\times\else\texttimes\fi{}{10}^{6}\text{ }\text{ }\ensuremath{\psi}(3686)$ events collected at $\sqrt{s}=3.686\text{ }\text{ }\mathrm{GeV}$ with the BESIII detector at the Beijing Electron-Positron Collider II, we search for the rare decay $J/\ensuremath{\psi}\ensuremath{\rightarrow}\ensuremath{\phi}{e}^{+}{e}^{\ensuremath{-}}$ via $\ensuremath{\psi}(3686)\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}J/\ensuremath{\psi}$. No signal events are observed and the upper limit on the branching fraction is set to be $\mathcal{B}(J/\ensuremath{\psi}\ensuremath{\rightarrow}\ensuremath{\phi}{e}^{+}{e}^{\ensuremath{-}})<1.2\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}7}$ at the 90% confidence level, which is still about one order of magnitude higher than the Standard Model prediction.
