“…We have previously discussed this for both transition metal [18] and main-group [19] derivatives, and have concluded that the lower frequency 19 F NMR resonance corresponds to the fluorine centre trans to the metal/metalloid, based upon the comparable magnitudes of M-19 F satellite couplings within trifluorovinyl and 1-chloro-2,2-difluorovinyl homologues. Application of the same arguments here results, unusually, in the assignment of the resonances, d trans > d cis , however, this is consistent with that reported previously for Hg(CCl@CF 2 ) 2 and ClHg(CCl@CF 2 ) [13]. Assignment of the fluorovinyl 13 C NMR resonances is in each case unequivocal, being based upon the observation of two large J CF coupling constants for the CF 2 centre.…”

“…The compounds RHg(CX@CF 2 ) (X = F, R = Ph 1, ðC 5 H 5 ÞFeðC 5 H À 4 ÞðFcÞ 2; X = Cl, R = Ph 3, Fc 4) were prepared by the low temperature (À78°C) reaction of the appropriate organomercurihalides RHgCl (R = Ph, Fc), with an excess of the lithium reagents LiCX@CF 2 (X = F, Cl), which are generated in situ from HFC-134a (CF 3 CH 2 F) and HCFC-133a (CF 3 CH 2 Cl), respectively, as previously described [16,13]. In this way the compounds 1, 2 and 4 were obtained, after non-aqueous work-up, in good yields, as high purity crystalline solids, which exhibit good stability under ambient conditions and can be stored for prolonged periods in the exclusion of light.…”

“…are fluorine-containing materials, methods of introducing fluorine into molecules always have potential value. Several stable compounds of fluorine have been developed by scientists [13] using environmentally friendly CFC-replacements, such as HFCs. Prompted by favourable research work and our interest in the field of organosilicon complexes, two ligands and their silicon complexes were screened against several pathogens.…”

“…[11] More recently, Brisdon and co-workers have prepared and structurally characterised the vinylgold() complexes [AuCR=CF 2 (PPh 3 )] (R = Cl, F) by treating [AuCl(PPh 3 )] with the organolithium reagent CF 2 =CRLi. [12] Puddephatt and Treurnicht reported the synthesis of the very thermally unstable vinylgold() complex [Au(CH=CH 2 )(CNMe)], which could only be characterised by 1 H NMR spectroscopy at -20°C. [13] Other approaches for adding vinyl groups to an AuPPh 3 unit have also been investigated.…”
