Rearrangement in a Tripodal Nitroxide Ligand to Modulate the Reactivity of a Ti-F Bond
Boreen, Michael A.,Bogart, Justin A.,Carroll, Patrick J.,Schelter, Eric J.
, p. 9588 - 9593 (2015)
The tripodal nitroxide ligand [(2-tBuNO)C6H4CH2)3N]3- (TriNOx3-) binds the Ti(IV) cation and prevents inner-sphere coordination of chloride in the complex [Ti(TriNOx)]Cl (1). The ligand undergoes an η2-NO to κ1-O rearrangement to enable a fluoride ion to bind in the related complex Ti(TriNOx)F (2). Computational and reactivity studies demonstrated that the ligand rearrangement contributed to the enthalpy change in the transfer of a fluoride anion.
A Facile Preparation of Rubidium and Caesium Selenocarboxylates
Kawahara, Yasuyuki,Kato, Shinzi,Kanda, Takahiro,Murai, Toshiaki,Ishihara, Hideharu
, p. 277 - 278 (1993)
Treatment of O-trimethylsilyl selenocarboxylates with rubidium and caesium fluorides affords rubidium and ceasium selenocarboxylates in good yields.
Synthesis and characterization of (2,6-difluorophenyl)xenone(II) and bis(2,6-difluorophenyl)iodine(III) trifluoromethanesulfonates
Naumann, Dieter,Gnann, Robert,Padelidakis, Vasilios,Tyrra, Wieland
, p. 79 - 82 (1995)
The reactions of bis (2,6-difluorophenyl)iodine(III) and 2,6-difluorophenylxenon(II) tetrafluoroborates with trimethylsilyl trifluoromethanesulfonate yield the corresponding bis (2,6-difluorophenyl)iodine(III) and (2,6-difluorophenyl)xenon(II) trifluoromethanesolfonates.The products were identified by NMR and vibrational spectroscopy as well as by mass spectrometry.The cation peak of an organoxenon compound has been detected for the first time by FAB mass spectrometry. - Keywords: Synthesis: (2,6-Difluorophenyl)xenon(II) trifluoromethanesulfonate; Bis(2,6-difluorophenyl)iodine(III) trifluoromethanesulfonate; NMR spectroscopy; FAB mass spectrometry
ON THE NON-EXISTENCE OF TRIMETHYLSILYL TETRAFLUOROBORATE IN ACETONE AND ACETONITRILE : THE GENERATION OF BORON TRIFLUORIDE IN WEAKLY COORDINATING SOLVENTS
Bassindale, Alan R.,Stout, Tim
, p. 1631 - 1632 (1984)
The recently proposed preparation of trimethylsilyl tetrafluoroborate actually gives trimethylfluorosilane and boron trifluoride coordinated to acetone or acetonitrile.
BEITRAEGE ZUR CHEMIE DES IODPENTAFLUORIDS TEIL II. IOD(V)-VERBINDUNGEN MIT α,ω-DIFUNKTIONELLEN ALKOHOLATEN
Frohn, Hermann Josef,Pahlmann, Wolgang
, p. 243 - 256 (1984)
Nucleophilic subsitution reactions if iodine pentaflurode with a series of homologous bifunctional alcoholates -(CH2)nO- (n=2,3,4,5,6,12), a geminal dialcoholate CCl3CH(O-)2 and a trifunctional alcoholate CH3C(CH2O-)3 protected by (CH3)3Si - groups are reported.Systems with short CH2 - chains (nX (X = SiMe3, IF4) which rearrange to mononuclear chelates IF3 of high stability.Dialcoholates with long CH2-chains (n>4) behave as bridging ligands forming stable multinuclear compounds IF4IF4 and (IF3)m (m>2). 1,4-Butanediolate is on the border line of the two systems.Products with greater subsitution IF2 (n=2,3) and IF2(OCH2)3CCH3 are also characterized.The dependence of 19F-NMR-shifts on the nature and arrangement of ligands is discussed.
Synthesis of [1-14C]-2,2-difluoroethene from [14C]-formaldehyde
Ruzicka,Qiu,Baker,Burton
, p. 59 - 65 (1994)
[1-14C]-2,2-Difluoroethene was synthesized from [14C]-formaldehyde using a modification of the Wadsworth-Emmons reaction, via formation of the intermediate (EtO)2P(O)CF214CH2OSiMe3. This highly volatile product was collected in a liquid nitrogen trap at a purity of >97% and specific activity of 0.2 mCi/mmol, with yields of 10-15%.

PROCESS FOR PRODUCING SULFONIC ACID GROUP-CONTAINING MONOMER
-
, (2021/01/22)
The present disclosure is directed to provide a process capable of producing a sulfonic acid group-containing monomer in a good yield, which can be used as a raw material of fluorine-based polymer electrolytes, such as membranes for fuel cells, catalyst binder polymers for fuel cells, and membranes for chlor-alkali electrolysis. A process for producing a sulfonic acid group-containing monomer represented by the general formula (3) includes the step of mixing and stirring a cyclic compound represented by the general formula (1) and a silanol compound represented by the general formula (2).
