Iron -, hexafluorophosphate

Experimental Procedure 2.1.3. Preparation of an Iron Carbene Complex by a-Abstraction of Hydride Dicarbonyl(T 5-cyclopentadienyl)(phenylthiocarbene) iron hexafluorophosphate [179]... 

Retrosynthetic analysis of the carbazomycins C (263) and D (264) based on the iron-mediated construction of the carbazole framework leads to tricarbonyl [3-methoxy-(l-5-ri)-cyclohexadienyl]iron hexafluorophosphate (779) and the aryl-amines 780a and 780b (see Scheme 5.84) as synthetic precursors (611). The arylamines 780a and 780b have been used previously as precursors for the total syntheses of carbazomycin A (260) and B (261) (see Schemes 5.86, 5.87 and 5.88).

Cyclopentadienyl)dicarbonyI(phenylthio)carbenium]iron hexafluorophosphate, Cp(CO)2Fe+=CHSC6H5 PF6 (1, m.p., 126°). This stable, crystalline phenylthio iron carbene is obtained in 80% yield by reaction of NaCpFe(CO)2 with CICHjSCftHs and then with (Qfy C+PF -.1... 

Cationic polymerization of thiiranes CMT (9-(thiiran-2-ylmethyl)-9//-carbazole) 217 and PMT (10-(thiiran-2ylmethyl)-1077-phenothiazine) 218 was studied by a Lithuanian group <2002JPH63>. Initiators were di-(/-butylphenyl)iodonium tetrafluoroborate (BPIT), diphenyliodonium tetrafluoroborate, cyclopropyldiphenylsulfonium tetrafluoroborate, and ( 7 -2,4-cyclopentadien-1 -yl) [1,2,3,4,5,6- )-( 1 -methylethyl)benzene]-iron(- -)-hexafluorophosphate(—1). The influences of temperature and initiator concentration on the polymerization rate and the conversion limit were determined. The values of initiator exponent and activation energy for the photopolymerization of CMT and PMT initiated with BPIT in 1,2-dichloroethane was established.

Add the solution of ammonium hexafluorophosphate to the saturated tetrafluoroborate solution, and leave standing at room temperature for 30 min. Filter the resultant precipitate, wash with water (2x5 mL) and dry under vacuum to give in the order of 6 g of tricarbonyl(4-methoxy-1-methylcyclo-hexadienylium)iron hexafluorophosphate as a yellow solid, displaying appropriate spectroscopic data. ... 

High-frequency shoulders on Vs(CO) and Vas(CO) bands in the FTIR spectra of an organometallic probe derived from tricarbonyl(l-4- n -5-pyridinocyclohexa-l,3-diene)iron hexafluorophosphate have been observed io on incubation with a-chymotrypsin and were assigned to an iron-complex covalently bonded to enzyme-NH2 groups. Curve-fitting analysis of the spectra enabled the bound complex to be detected even in the presence of the unbound probe and its FTIR spectrum to be calculated and compared with spectral data arising from similar interactions between the tricarbonyliron moiety and twelve aminoacids and polylysine.
