BACKGROUND The aim of our work was to compare two methods, both based on direct transmethylation with different reagents, BF3/MeOH (boron trifluoride in methanol) or HCl/MeOH (hydrochloride acid in methanol), in acid catalysis, without prior extraction, to find the fast, non-expensive but enough precise method for 9 principal fatty acids (lauric, myristic, palmitic, stearic, oleic, linoleic, li...

An accurate value for the heat of formation of boron trifluoride is of significant importance because this value is involved in the thermochemistry of many boron compounds. The study of the thermochemistry of boron compounds was for a long time hampered by difficulties in measuring a suitable reaction involving elemental boron. The heat of formation of boric oxide, for instance, was uncertain t...

The reaction of (trimethylsilyl)acetylene with the phosphinito phosphanido Pt(I) complex [(PHCy2)Pt(μ-PCy2){κ2P,O-μ-P(O)Cy2}Pt(PHCy2)](Pt-Pt) (1) results in the protonation of the Pt-Pt bond with the formation of the bridging hydride complex [(PHCy2)(Me3SiC≡C)Pt(μ-PCy2)(μ-H) Pt(PHCy2){κP-P(O)Cy2}](Pt-Pt) (2), which was characterized by spectroscopic, spectrometric and XRD analyses. Complex 2 ex...

Deprotonation of the parent titanium imido ((tBu)nacnac)Ti≡NH(Ntolyl2) ((tBu)nacnac(-) = [ArNC(t)Bu]2CH; Ar = 2,6-(i)Pr2C6H3) with KCH2Ph forms a rare example of a molecular titanium nitride as a dimer, {[K][((tBu)nacnac)Ti≡N(Ntolyl2)]}2. From the parent imido or nitride salt, the corresponding aluminylimido-etherate adduct, ((tBu)nacnac)Ti≡N[AlMe2(OEt2)](Ntolyl2), can be isolated and structura...

A new class of 4H-imidazoles was synthesized starting from fused-ring aromatic dinitriles. Strong bathochromic shifts of the longest wavelength absorptions were observed in the corresponding UV/vis spectra due to a conversion of the merocyanine chromophores into cyanines/(aza)oxonoles upon protonation/deprotonation of the 4H-imidazoles. Novel boratetraazapentalenes were synthesized via a cycliz...

We synthesized polythiophene (PTh) films on stainless steel electrodes using chronoamperometry in boron trifluoride diethyl etherate (BFEE) electrolyte with anionic surfactants. The presence of the anionic surfactants in BFEE reduced the oxidation potential of thiophene and increased the oxidation current during electropolymerization. The measured in-plane electrical conductivity of PTh films s...
