The synthesis of an ethylenic orthoester of sucrose by transorthoesterification of an acrylic reagent with sucrose is described. Mild hydrolysis of this orthoester gave sucrose selectively monosubstituted by an acryloyl group at either the 4-O-or the 6-O-position. These acrylates were homopolymerize
Wittig reagents 1a,b react with dicyanomethylene derivatives of fluorenone (3) and xanthone (4) to give the corresponding phosphoranylidenecyclobutylidene adducts 6a, 6b, 9a, and 9b. On the other hand, the reaction of Wittig-Horner reagents (2) with the same nitriles 3 and 4 afforded the respective
