The reactions of vicinal dinitro compounds with tin(II) chloride have been studied. The reactions of α,β-diaryl vicinal dinitro compounds and tin(II) chloride in polar solvents gave the corresponding olefins in good yields. The aliphatic vicinal di

It was found that TeCl4 in methylene chloride (containing tetrabutylammonium perchlorate as a supporting electrolyte) is reduced to TeCl2, Te0 and Te−2 in potential applied. Two reduction waves are observed during the reduction of TeCl4 at a platin

Various basic esters of nitrogen (2) and carbocyclic (3 and 4) analogs of cannabinoids were synthesized using dicyclohexylcarbodiimide in methylene chloride. The compounds in the three series werw studied in selected pharmacological tests in mice, ra

The molecular structure of 2-furoyl chloride has been investigated by gas-phase electron diffraction at 86°C. Two distinct conformers were identified, a more stable planar form with the furan oxygen and the carbonyl oxygen syn and a less stable plan

Rate constants and activation parameters for the aquation of tris(5-nitro-1,10-phenanthroline)iron(II) in hydrogen peroxide–water mixtures (mole fraction of hydrogen peroxide = 0.015–0.15) have been determined. The variations of these kinetic par

A general method was worked out for the preparation of highly optically pure β-substituted alkanoic acids from aldehydes with use of (2R,3S)-6-alkylidene-3,4-dimethyl-2-phenylperhydro-1,4-oxazepine-5,7-diones(2) as key intermediates. Oxazepines(2) w

The infrared spectra of the formaldehyde complexes with hydrogen bromide, chlorine and iodine chloride have been studied. The CH-stretching fundamentals of formaldehyde undergo significant blue shifts in these complexes. The shifts are larger in nitr
