The first easily reproduced solution-phase synthesis of K{sub x}C{sub 60} and the confirmation of T{sub c} at 18.0+-0.1K are reported herein. The reduction of C{sub 60} in solution with excess K was found to lead to a superconducting K{sub x}C{sub 60} rather than a highly resistive material as expected. The solution method of preparation is much simpler that the vapor-phase K transfer and reaction. The actual compound composition is not yet known. 17 refs., 2 figs.
