What do we know about the Grubbs catalyst?
Ring-closing kinetics:[2]
Addition of CuCl or CuCl2 speed up reaction
(Cu acts as a phosphine scavenger)
Structure of starting catalyst:[2][3][4]
Activity for various ligands:[2]
L=> PCy3>PiPr3>PCy2Ph>PiPr2Ph>>PPh3
X tends to be small and electronegative
L tends to have large cone angle and be electron donating
