Perfluorovinyl–metal derivatives: a new one-pot synthesis

The synthesis and structural characterisation of an homologous series of group 14 1-chloro-2,2-difluorovinyl compounds

“…In each case, the numbering scheme for the second molecule of the asymmetric unit is obtained by adding 20 to each atom label. (6) were solved by direct methods and subjected to full-matrix least-squares refinement on F 2 using the SHELX-97 [15] program. Structures were corrected for absorption by the multi-scan method using the SORTAV program.…”

“…We have applied this approach to the preparation of organometallic systems, [6] in pursuance of our interest in the structural characteristics of unsaturated fluoro-organometallic compounds, and the possibility of deriving more versatile synthetic reagents. A variety of transition-metal trifluorovinyl derivatives have thus been investigated structurally, [7] and most recently our attention has turned to the study and derivatisation of main-group systems [8].…”

An efficient room temperature preparation of bromo difluorovinylzinc reagent (CF2CBrZnCl) and a high yield one-pot synthesis of α-bromo-β,β-difluorostyrenes

“…Recently HFC-134a and HCFC-133a have been identified as excellent synthetic precursors for the generation of trifluorovinyllithium and a-chloro-b,b-difluorovinyllithium reagents at low temperature (Scheme 3) [22][23][24]. Various groups have demonstrated the synthetic potential of the trifluorovinyl or chlorodifluorovinyl anions thus generated, making them excellent alternatives for CF 2 ¼CFX or CF 2 ¼CX 2 [25][26][27][28].…”

Pentamethylcyclopentadienyl rhodium(III) trifluorovinyl phosphine complexes and attempted intramolecular dehydrofluorinative coupling of pentamethylcyclopentadienyl and trifluorovinyl phosphine ligands

“…Following the development of a convenient synthetic route to [CF 2 CF] À Li + from the readily available HFC-134a (CF 3 CH 2 F), and subsequent syntheses of trifluorovinylphosphines R 3Àx P(CF CF 2 ) x [14][15][16], a number of complexes of trifluorovinylphosphines with molybdenum [15], platinum [15,17] and gold [15] have been reported over the past decade.…”
