Abstract. A two-step synthesis of trans,trans,trans-[RuCl2(CNBut)2(PPh3)2] is described in which the first step uses a microwave reflux to make [RuCl2(PPh3)3] and the second step is the room temperature addition of t-butylisocyanide to a solution of the isolated [RuCl2(PPh3)3]. The final product is isomerized to the cis,cis,trans-isomer in the solid state. The progression of this reaction at a fixed temperature within the 140 C150 C range can be monitored by solution 1H NMR spectroscopy.
