An efficient use of triphosgene, as an acid activator, for the synthesis of substituted azetidin-2-ones via ketene-imine cycloaddition reaction using various acids and imines have been described.
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.
Difluoromethylation of Methyl Aryldithiocarbamates
Petko,Yagupol'skii
, p. 670 - 672 (2007/10/03)
Reactions of methyl aryldithiocarbamates with chlorodifluoromethane in 10% NaOH in the presence of tetrabutylammonium hydrogen sulfate at 0-30°C give methyl difluoromethyl arylimidodithiocarbonates and, in low yields, methyl N-aryl-N-difluoromethyldithioc
