 addition 
 of the carbon  
 fluorine bond of a series of perfluorinated 
 and polyfluorinated arenes across the mg  mg bond of a simple 
 coordination complex proceeds rapidly in solution . 
 the reaction results 
 in the formation of a new carbon  
 magnesium bond and a new fluorine  magnesium 
 bond and is analogous to grignard formation in homogeneous solution .
