Surfactant pillared clays as phase-transfer catalysts : a facile synthesis of alpha-azidoketones from alpha-tosyloxyketones and sodium azide
The use of inexpensive and recyclable phase-transfer catalysts, surfactant pillared clays, is demonstrated in a simple and highly efficient synthesis of alpha-azidoketones from readily accessible alpha-tosyloxyketones and sodium azide.
