A method of polarization spectroscopy for a conducting surface characterized by a high sensitivity to the state of the surface and its transition layer is proposed. The method uses excitation of surface electromagnetic waves (SEWs) by a linearly pola

A mass-spectral study was carried out on the behavior of the Z- and E-isomers of 9-picolylideneazafluorenes. A possible mechanism for the elimination of a hydrogen atom from the M+ ion of the Z- and E-isomers of 1(4)-azafluorene derivatives was exami

Oxidation of 4-phenyl-, 4-(4-pyridyl)-, and 4-phenethenyl-1,2,3,6-tetrahydropyridines with potassium permanganate can stop at the stage of the introduction of an oxo group into the allyl C(2) position of the piperideine fragment. In contrast to their

The condensation of aromatic aldehydes with indolo[2,1-a]isoquinoline in a solution of trifluoroacetic acid yielded a series of 12-arylidenindolo[2,1-a]isoquinolinium trifluoroacetates. Analogous quaternary salts are formed with trichloroacetic and a
