Structure of C, N-chelated nButyltin(IV) fluorides and their use as fluorinating agents of some chlorosilanes, chlorophosphine and metal halides

The tin atom in the solid-state structure of {2-[(CH3)2NCH2]C6H4}nBu2SnF is five coordinated with carbon atoms in equatorial and fluorine and nitrogen atoms in axial positions. The fluorina

New General Synthesis of Organophosphorus P-F Compounds via Reaction of Azolides of Phosphorus Acids with Acyl Fluorides: Novel Route to 2-Deoxynucleosidyl Phosphorofluoridates and Phosphorodifluoridates

Tetra- and tri-coordinate P-N-imidazole derivatives and their structural analogous react smoothly with acyl fluorides to give the corresponding P-F compounds an almost quantitative yield.This method has been successfully applied to produce 2-deoxynucleosidyl phosphorofluoridates and phosphorodifluoridates.

Phenylfluorophosphoranes: axial-equatorial fluorine exchange in RC6H4PF3H and intermolecular exchange in the PhPF2(H)OMe-MeOH-base system

Activation parameters for axial-equatorial fluorine exchange in arylfluorophophoranes PC6H4PF3H, where R = o-CF3, m-CF3, m-CH3, were studied by the dynamic nmr technique. Δ G298(excit.) varied between 53 and 56 kJ mol-1.The synthesis of difluoromethoxyphenylphosphorane, PhPF2(H)OMe, from PhPF2 and MeOH is catalyzed by small amounts of Et3N, pyridine, PhPF3H, or HF.Rapid intermolecular ligand exchange occurs in PhPF2(H)OMe after addition of methanol and a base such as triethylamine or pyridine.Under these conditions, exchange of fluorine, hydrogen, and methoxy ligands occurs, as shown by 1H, 19F, and 31P nmr.From a line shape analysis of the 31P nmr spectrum, the rate of P-F cleavage was found to be first order (1.17 +/- 0.2) in Et3N concentration, with Δ G(excit.)298 = 50 kJ mol-1 and Δ S (excit.) = -67 J mol-1 deg-1.An equilibrium constant of 1.8 at 25 deg C was found for the reaction of PhPF2(H)OMe with PhPF2.

A NEW APPROACH TO THE SYNTHESIS OF ARYLDIFLUOROPHOSHINES. FORMATION OF CIS-DICHLORO-BIS(ARYLDIFLUOROPHOSPHINE)PLATINUM(II) COMPLEXES

Reaction of chlorodifluorophosphine with aryllithium compounds has been found to furnish aryldifluorophosphines.This type of reaction is applicable to any aromatic system for which a regioselective lithiation is possible.The most stable products are those

CHLOR-FLUOR -AUSTAUSCHREAKTIONEN MIT TRIALKYLFLUOR-PHOSPHORANEN

Trialkyldifluorophosphoranes R3PF2 (R = iPr, nBu) were found to react with chlorides or organoelement chlorides, EClm or ERm-zClz (EIV, m = 4, z = 1,2; EV, m = 3, z = 1,2) of elements belonging to main groups IV and V with chlorine/fluorine exchange to form the halophosphonium salts +Cl- (X = F, Cl) and the fluoro derivatives, EFm or ERm-zFz.With AlCl3 ionic products of composition are obtained.The transition metal chlorides, NiCl2, PdCl2 NiCl2(PMe3)2, and CoCl2 were found to be less reactive.Chlorine/fluorine exchange has been observed only the case of CoCl2.
