(Chemical Equation Presented) The trajectories for nucleophilic substitutions at sulfur(VI) and sulfur(II) have been investigated by the endocyclic restriction test. On the basis of double-labeling experiments, the sulfur(VI) transfer in the conversion of 1 to 2 is found to be intramolecular, while the sulfur(VI) transfer in the conversion of 3 to 4 and the sulfur(II) transfer in the conversion of 5 to 6 are found to be intermolecular. These results are taken to be consistent with transition structures for these sulfur transfer reactions which require a large angle between the entering and leaving group, a geometry analogous to apical group positions in trigonal bipyramidal transition states.

Reactions of 2-(phenylthio)benzyl chloride with dimethylamine, diethylamine, pyrrolidine, piperidine, morpholine, and 1-methylpiperazine afforded the title compounds VI-XI.Reaction of 2-(phenylthio)benzaldehyde with nitromethane gave the nitrostyrene XIV which was reduced with lithium aluminium hydride to 2-(2-phenylthio)phenyl)ethylamine (XVI).This was transformed to the N-methyl and N,N-dimethyl derivatives XVIII and XIX.The Claisen reaction of (2-(2-phenylthio)phenyl)acetonitrile with ethyl acetate afforded the compound XXI which was cleaved by phosphoric acid to (2-(phenylthio)phenyl)acetone (XX).The Leuckart-Wallach reaction afforded the formamide XXIII which was used as starting material for preparing the amines XXIV-XXVI.The alternative approach to these compounds starting by reaction of the aldehyde XII with nitroethane was complicated by the fact that in addition to the nitropropene XV 2-(phenylthio)benzonitrile was also formed.The synthetic use of the inhomogenous XV resulted then in mixtures of amines XXIV-XXVI with IV-VI which was followed by means of mass and 1H NMR spectra.The amines XXIV-XXVI were oxidized to the sulfoxides XXVII-XXIX.The oily bases were transformed to crystalline salts and spectra of all homogeneous bases were recorded.Pharmacological testing showed the amine VI (VUFB-15370) to be a promising potential antidepressant.The amines XI and XXV showed also pharmacological profile of potential antidepressant.
