Rare decay modes J/psi -> D(S)(-)pi(+) + c.c., J/psi -> D(-)pi(+) + c.c., and J/psi -> D(0)K(0) + c.c. are searched for using 5.77 x 10(7) J/psi events collected with the BESII detector at the BEPC. No signal above background is observed. We present upper limits on the branching fractions of B(J/psi -> D(S)(-)pi(+)) < 1.3 X 10(-4), B(J/psi -> D(-)pi(+)) < 7.5 x 10(-5), and B(J/psi -> D(0)K(0)) < 1.7 x 10(-4) at the 90% confidence level.
