Reduction of alkylthiomethyleniminium iodides proceeds smoothly by use of trimethoxysilane and dilithium 2,3-butandiolate in tetrahydrofuran at 0 deg C to give the corresponding S,N-acetals selectively in high yield.

Simple N-monosubstituted thioamides react with acid hydrazides to form 1,2,4-triazole derivatives.N,N-Disubstituted thioamides alkylated with methyl iodide readily yield with acid hydrazides 1,3,4-oxadiazoles.

In reactions of methyliodides of N,N-disubstituted thioamides with 2-hydrazinoquinoline a series of new compounds have been obtained: iodohydrides, derivatives of 1-α-morpholinobenzylidene-2-quinolinohydrazine and of 1-α-piperidinobenzylidene-2-quinolinohydrazine.The compounds obtained, when transformed into free bases, undergo cyclization to derivatives of s-triazolo(4,3-a)quinoline system under the effect of glacial acetic acid.All these compounds have been characterized by means of UV and IR spectra.
