Relative reactirufies of: organornetallic c~:npounds. XI, etc. 585 required for reaction between phenylmagnesium bromide (0.05 mole) and benzonitrile (0.06 mole) from 0.31 hour to 0.13 hour. It is quite likely that these and other catalytic effects to be reported will be found applicable to many other organometallic reactions.T h e authors are grateful to Lloyd L. Heck for assistance.
