The following highly fluorinated nonpolar dendrimers were obtained in high yields from multiple hydrosilylation reactions between core hydride terminated carbosilane dendrimers and allyl-1,1-dihydrotrifluoroethyl ether or allyl-1,1-dihydroheptadecafluorononyl ether through divergent synthetic routes: Si[CH2-CH2SiMe2(CH2CH 2CH2OCH2CF3)]4 (7), Si{CH2CH2SiMe[CH2CH2SiMe(CH 2CH2CH2OCH2CF3) 2]2}4 (8), Si[CH2CH2Si(CH2CH2CH 2OCH2C8F17)3]4 (9), Si[CH2CH2SiMe2(CH2CH 2CH2OCH2C8F17)] 4 (10), and Si{CH2-CH2Si[CH2CH2Si(CH 2CH2CH2OCH2C8F 17)3]3}4 (11). These compounds were characterized by elemental and spectroscopic analyses. Valuable mass spectral data were obtained by using atmospheric pressure chemical ionization (APcI). The fluorinated dendrimer molecule and the nonfluorinated core scatter X-ray light differently and present unique slopes on the Guinier Plot of data from small-angle X-ray light scattering (SAXS) in hexafluorobenzene. Glass transition temperatures (Tg) and thermogravimetric analyses (TGA) of the dendrimers were determined.

α,α-Difluoroacylsilanes were synthesised directly from a range of allyl ethers of trifluoroethanol via dehydrofluorination/metallation procedures, followed by thermal [3,3]-sigmatropic rearrangement of the intermediate vinylmetals. The scope and limitatio

(Chemical Equation Presented) Direct precursors to analogues of pentopyranoses, 6-deoxyhexoses, and hexoses, in which a CF2 center replaces the pyranose oxygen, have been synthesized rapidly from trifluoroethanol. A simple scaleable allylation
