    • Neither THF nor acetone were effective sovents for the cyclization. The reason for the difference in the efficiency of the fluorinated alcohols and the other polar solvents is unclear.

    • Rhodium chloride complex such as Willkinson's catalyst accelerates the [4+2] cycloadditon of 1,3-diene-8-yne or 1,3,8-triene derivatives in TFE. It has been suggested that TFE enhances the polarizability of the Rh-Cl bond. See, Refs. 13a and 13d.
