An efficient synthesis of 2-arylamino-2-imidazolines from dimethyl N-aryldithioimidocarbonates and ethylenediamine on solid support under microwave irradiation has been developed. The reaction time has been reduced from hours to minutes with improved yiel
The efficient synthesis of 2-arylamino-2-imidazolines, 2-heteroaryl- substituted benzimidazoles, and their morpholin-4-ylmethyl derivatives

2-Heteroaryl-substituted 1H-benzimidazoles were synthesized in good yields by heating the HSO3 adducts of heteroaromatic aldehydes with o-phenylenediamine in DMF under reflux. This procedure is more general and shorter than earlier methods. 2-Arylamino-2-imidazolines were prepared by heating dimethyl aryldithioimidocarbonates and ethylenediamine under reflux. The imine-enamine tautomerization of 2-arylamino-2-imidazolines was investigated by means of 1H-NMR spectroscopy. Morpholin-4-ylmethyl derivatives of the benzimidazole and imidazoline products were synthesized regioselectively by treatment with morpholine and formaldehyde.

S-Trimethylsilylmethyl carbonimidodithioate derivatives (2-5) prepared by an addition of trimethylsilylmethanethiol (1) toward the isothiocyanate followed by S-alkylation were found to react with various carbonyl compounds in the presence of fluoride ion to give oxathiolane derivatives (6-9) in moderate yields, in which the silylated carbonimidodithioate derivatives formally served as thiocarbonyl ylide equivalents.
