The evacuation and inert gas introduction apparatus capable of quickly switching over between the evacuation state and the inert gas introduction state, is provided for a synthesizing device for molecular asymmetrical catalysts. The evacuation line is connected to a vacuum pump via a cock and solvent trap. The inert gas introduction line is connected to an argon gas cylinder via a cock. The vacuum cavity is provided at a tip end of the housing of the three-way cock, and thus the inside plug is attracted towards the vacuum cavity. The evacuation line is connected to the first port of the three-way cock, the inert gas introduction line is connected to the second port and the each reaction chamber of the synthesizing apparatus is connected to the third port. As the rotation angle of the inside plug is changed, the connection state of the line is switched.
