A very efficient and reusable catalyst has been developed for the on-water nucleophilic substitution of alkyl halides and tosylates with azide or thiocyanate in excellent to quantitative yields. The reaction proceeds smoothly and cleanly without any organic cosolvent or other adductive, and the brush can be reused at least 10 times without noticeable loss of the catalytic activity. The high efficiency, simplicity of product and catalyst isolation, outstanding recyclability, and organic-solvent-free conditions show promise for the use of this catalyst in the laboratory and in industry.

In a method of carrying out organic conversions via heterogeneous phase transfer catalysis by contacting immiscible liquid phases containing respective substances capable of interacting, with a solid catalyst to promote the transfer of reactive species from one liquid phase to another, the improvement comprises employing as catalyst a cation exchanged form of a 2:1 layered silicate clay with layer charge densities in the range of above 0.4 to 2.0 containing an onium ion containing one or more alkyl hydrocarbon chains and maintaining the materials in emulsified form by having a sufficient chain length of an alkyl group relative to the charge density of the clay.
