It is thiazolidene-2-imine and not imidazole-2-thione as the reaction product of 1-benzoyl-3-phenylthiourea with Br2/enolizable ketone

[GRAPHICS] The products obtained by the reaction of benzoyl-3-phenylthioureas with bromine and enolizable ketones in the presence of triethylamine are not imidazole-2-thione derivatives as reported (Org. Lett. 2003, 5, 1657 - 1659) rather they are thiazolidene-2-imine derivatives.
