Seventy-two novel 1,3,4-oxadiazole thioether derivatives containing different flexible-chain moieties were designed and synthesized. The nematicidal activities of all the title compounds were evaluated, and some compounds showed excellent nematicidal acti

Diaryl disulfides were reduced efficiently by a Zn/Cp2TiCl 2 system at room temperature in dry THF to give the corresponding nucleophilic sulfur anion-titanocene complex, followed by reaction with α, β-unsaturated esters (ketones or nitriles) to afford the corresponding β-arylthioesters(ketone or nitrile) in good yields.

Disulfide has been reduced by cerium trichloride and samarium in tetrahydrofuran to produce samarium thiolates. The "living" species reacts smoothly with α,β-unsaturated esters(nitriles) to afford β-thioesters(nitrile) under mild and neutral conditions. The new thiolate anion also reacts with acyl halides, anhydrides and alkyl or benzyl halides to give thioesters and sulfides, respectively.

Anodic peak potentials for 42 anionic nucleophiles are reported along with the rate constants for the reactions of the anions with benzyl chloride.By comparing these rate constants with those of the reactions of outer-sphere electron-transfer reagents (radical anions), it has been demonstrated that the reactions of the anions with benzyl chloride are typical single-step SN2 reactions as opposed to a two-step process comprising dissociative single electron transfer (SET) to benzyl chloride followed by radical combination.The data suggest that very electron-rich nucleophilic anions with potentials of -1.5 to -2.2 V (and more negative) with respect to the ferrocenium/ferrocene couple might participate in a SET reaction.The 42 anions studied included representatives of four classes of nucleophiles, viz. sulfur-, carbon-, oxygen- and nitrogen-centred anions.The previously observed correlation of rate constants and anodic peak potential was again found for these anions with the most reactive species having the most negative peak potentials.Correlations by class indicate that the sensitivity of rate constants to changes in peak potential is greatest (and equivalent) for the sulfur-, carbon- and oxygen-anions and for representatives with the same peak potential, the rate constants by class follow the order sulfur > carbon > oxygen.The nitrogen nucleophiles show a significantly lower sensitivity of rate constant to changes in peak potential than do the other three classes.

Ethyl 3-chloro-3-(3,4-dichlorophenylthio)propanoate (8) reacted with electron-rich arenes in the presence of titanium tetrachloride to give the Friedel-Crafts products 10a-13a. Reactions of 8 with 1-trimethylsilylalkynes 14a-d were effected with aluminum chloride to afford the substitution products 15a-d. Some chemical transformations of the products are also described.
