A reaction of SH-containing heterocycles with dimethyl carbonate (DMC) in the presence of K2CO3 and tetrabutylammonium bromide (Bu4NBr) gave heteroaryl methyl thioethers in 44-93% yields. The reaction was carried out under mild conditions. This method provided a useful synthetic method for preparation of various heteroaryl methyl thioethers without the use of toxic methylic halides or dimethyl sulfate.

Spectrophotometric studies of adducts obtained by reacting molecular iodine and some benzazole-2-thione and -2-selone derivatives have been carried out in CH2Cl2 solutions.The termodynamic and spectral characteristics of these complexes have been determined.Except for benzoxazole-2-selone and 3-methylbenzthiazole-2-selone, at least one isosbestic point has been found in the spectra of all the compounds, indicating the formation of 1:1 molecular adduct.This model, employed for the calculation of the stability constants, fits the experimental data well in all cases.A non-linear least-squares method has been used for the calculation, and attention has been taken in selecting the experimental points to improve the reliability of the K and ε values.
