Some nonionic detergents aggregate in organic solvents to form reversed or inverted micelles. lP2 The central part (core) of the micelle contains the oxyethylene groups of the surfactant and is the site of solubilization and chemical reactions. Little attention has been given to catalysis by nonionic reversed micelles, although the results may be easier to rationalize due to the absence of the complicating ion-exchange proce~ ses.~ Additionally ...
