INTRAMOLECULAR PHOTOCYCLOADDITION OF NONCYCLIC POLYETHER COMPOUNDS CONTAINING alpha , omega -DICINNAMATES END GROUPS AND UPTAKE OF ALKALI METAL THIOCYANATES WITH THEM.

Article abstract of DOI:10.1246/bcsj.57.2657

Noncyclic polyethers containing two cinnamoyl end groups have been prepared; they were cyclized by photosensitized intramolecular addition. The uptake of alkali metal (sodium and potassium) thiocyanates with these compounds and their ability to extract ha
