Fluoroaliphatic esters of fluorosulfonic acid. 4. Reactions of ?-fluorosulfatoperfluoro ketones with nucleophilic reagents
摘要:
alpha-Fluorosulfatoperfluoroethyl isopropyl ketone I and fluorosulfatopentafluoroacetone II react with alkali metal chlorides and bromides to form the corresponding alpha-haloperfluoro ketones as a result of direct nucleophilic substitution.

The synthesis of some 7,7-difluoro-7,8-dihydropterins and pterins with fluoroalkyl subsitutents at the 6 or 7 positions from fluorine-containingaliphatic precursors and suitably substituted pyrimidines is described. The fluorine-containing pterins were found to be very insoluble and also stable to nucleophiles and bases in dilute aqueous solution.

Hexafluoroacetone and other polyfluorinated ketones react with boron halides, organoboron halides, and alkylthioboranes to form a wide range of perhalogeno-organicborates and related compounds.

Hexafluoroacetone, monochloropentafluoroacetone, and dichlorotetrafluoroacetone cause fission of the silicon–nitrogen bond in certain aminosilanes, to form the corresponding insertion products. Hexafluoroacetone is found to insert similarly into the germanium–nitrogen and the tin–nitrogen bond. Insertion into the silicon–nitrogen bonds of a diazasilacyclopentane also causes polymerization.

is described, and the postcoital and uterotropic activities of these 1-trifluoromethyl-1,2,2-triphenylethylenes are determined. The parent compound and 3 substituted analogs were prepared by the stepwise replacement of the vinylic F atoms of hexafluoropropene with aryl groups from ArLi reagents. The postcoital antifertility and uterotrophic activities in the rat were determined by treating rats with
