  The stereospecific synthesis of cis and trans diethylenic epoxides 5a-c is reported. Thermal rearrangement of cis epoxides gives 4,5-dihydro-oxepines 6a-c (3,3 sigmatropic reaction with boat transition state); the pyrolysis of the trans epoxides produces also 2,3-dihydro-furans 7a-c; the disrotatory ring closure of a carbonyl ylide is proposed to explain the stereospecific formation of dihydrofuranic

  A process for producing a substantially dry polymer particle powder. A mixture of polymerization reagents is formed from a mixture of at least one monomer source and a solvent selected from the group consisting essentially of water and organic solvents and an initiator source. The mixture of polymerization reagents is sprayed into a heated, controlled atmosphere, forming droplets of the mixture which are allowed to fall through the heated, controlled atmosphere for a sufficient period of time to obtain a desired degree of polymerization. The solvent is continuously evacuated from the atmosphere during the polymerization process.
