Cyclocondensation of n-(prop-2-yn-1-yl)- and n-(penta-2,4-diyn-1-yl)- o-phenylenediamines with phenyl isothiocyanate and carbon disulfide

The cyclocondensation of N-(prop-2-yn-1-yl)-o-phenylenediamines with phenyl isothiocyanate leads to the formation of 1-(prop-2-yn-1-yl)-1,3-dihydro-2H- benzimidazole-2-thiones irrespective of the substituent nature at the triple bond. Reactions of both mo

REARRANGEMENT OF 1-(2-PROPYNYL)BENZIMIDAZOLINE-2-THIONES TO 2H(4H)-1,3-THIAZINOBENZIMIDAZOLES

1-(2-Propynyl)-2-chlorobenzimidazoles were synthesized by the reaction of 2-chlorobenzimidazoles with propargyl bromide.When boiled with thiourea, they are converted into 1-(2-propynyl)benzimidazolin-2-thiones.When heated in an alcohol solution of potassium hydroxide, the latter rearrange to mixtures of isomeric 2H(4H)-1,3-thiazinobenzimidazoles.
