  Title Solvent-free synthesis of calix[4]resorcinarenes Type Journal Article
  Year 2001 Publication Green Chemistry Abbreviated Journal Green Chemistry  
  Volume 3 Issue 6 Pages 280-284  
  Keywords Calix[4]resorcinarenes; Synthesis; Resorcinol; Benzaldehyde; Solvent-free  
  Abstract Calix[4]resorcinarenes may be prepared in high yield and purity by direct reaction of resorcinol and benzaldehyde derivatives in the presence of a catalytic amount of solid acid and at ambient temperature under solvent-free conditions. This represents a viable alternative to traditional solution phase methodology. The solvent-free method measures up well with respect to energy usage, solvent wastes and associated hazards, reaction time and yield. In addition, the relevant benzaldehyde derivatives are prepared in polypropylene glycol, which is readily recycled.
