Some known bis(arene) complexes of zerovalent Ti, V, Cr, and Mo have been synthesised in a new way by stepwise reduction of solutions of the metal chlorides in tetrahydrofuran and arene, using K atoms condensed into the solutions at –110 °C under vacuum in a rotary reactor. The extent of reduction was followed by observing colour changes in the solutions. With Ti and V, the initial products were anionic
