    • One of the referees suggested the involvement of trifluoromethyltrifluoromethanesulfonate CF3OSO2CF3, which might form during the preparation of triflic anhydride, as a source of CF3 radicals. Although such a hypothesis cannot be fully eliminated at the present stage, we did not observe the formation of dimers during the interaction of triflic anhydride with the enol ether 12 in the absence of collidine.

    • note
    • Vinyl triflates have been prepared starting either from the corresponding ketones upon their interaction with triflic anhydride in the presence of an amine, in rather low yields (45%) or from the (TMS) enol ethers, via their lithium enolates [11]. Alkyl triflates were similarly obtained from the corresponding alkyl ethers and triflic anhydride [15]. The transformations of enol ethers into vinyl triflates observed herein will be described in a forthcoming paper.
