Results Formation of the n-Amylsodium-TMEDA Complex.-Addition of an approximately equimolar amount of TMEDA (see Experimental Section) to a suspension of n-amylsodium in hexane at-15” resulted in an apparent solubilization of the solid to give a bright blue solution. Centrifugation of a portion of this solution, however, gave a clear, supernatant liquid and a dark blue precipitate, indicating that the amine had a dispersing rather than a ...
