Chemistry of some model compounds related to fluorinated polymers [PDF]
, 1993 The work described in this thesis is concerned with three areas which are the generation of stable carbocations from saturated model compounds related to poly- vinylidenefluoride, the development of synthetic routes to fluoro-organo-phosphazenes with ...

Organo-sulfur phosphorus chemistry
, 1998 P-organo-substituted dithiadiphosphetane disulfides have been prepared by the reaction of ferrocene and arenes with P4S10. Reaction of these compounds and Lawesson's reagent with alkenes, 2,3-dimethylbutadiene and other compounds gave organo-sulfur ...

One-pot cross-enyne metathesis (CEYM)–Diels–Alder reaction of gem-difluoropropargylic alkynes
Beilstein Journal of Organic Chemistry, 2013 Propargylic difluorides 1 were used as starting substrates in a combination of cross-enyne metathesis and Diels–Alder reactions. Thus, the reaction of 1 with ethylene in the presence of 2nd generation Hoveyda–Grubbs catalyst generates a diene moiety ...

New methodology for the synthesis of fluorinated aromatics [PDF]
, 1990 This thesis is concerned with new methodology for the introduction of fluorine atoms, and trifluoromethyl groups into aromatic systems and the following approaches have been adopted: (i) The possibility of selective cleavage of the aryl-silicon bond of ...

Three step synthesis of single diastereoisomers of the vicinal trifluoro motif
Beilstein Journal of Organic Chemistry, 2009 A three step route to single diastereoisomers of the vicinal trifluoromethyl motif is described. The route starts from either syn- or anti-α,β-epoxy alcohols and takes a direct approach in that each of the three steps introduces a fluorine atom in a ...
