    • Signals for complex 2 can also been seen upon thermolysis of Ru(PPh3)2(CO)3 in the presence of excess I iPr2Me2 at 333 K, showing that the cis-NHC arrangement is not simply a kinetic phenomenon. However, the reaction is slow and leads to a number of other unidentifiable products being formed see ref 19
