5-(perfluoropropen-1-yl), 5-(perfluorocyclohexen-1-yl), and 5-(perfluorocyclopenten-1-yl). In these reactions, 2'-deoxy-5-(trimethylsilyl)uridine and 2'-deoxyuridine were also formed. The 5-substituted 2'-deoxyuridines were tested for activity against herpes simplex virus type 1. Compound 12 and the mixture of 15 and 16 had an ID50 of 20-26 micrograms/mL in Vero cells. The activity of the mixture resided
