    Abstract: Title compds. (I; R1 = halo, C1-4 alkyl, NO2, CN; R2 = NO2, CN, CF3; O, S; R3 = C1-4 alkyl; R4 = OH, C1-8 alkoxy C1-6 alkylthio, C1-2 alkenyloxy, C3-6 alkinyloxy; n = 1-3; m = 0-2), useful as herbicides, were prepd. by reacting phenoxy phenol(II) or corresponding chenolate with carboxylic acid (III; Hal = halo) in the pressence of acid-coupling agent. Thus, II was dissolved in methylethylketone, and K2CO3 and halogenocarboxylic acid ester were added, which were refluxed for 16 hr, cold water added, treated with methylene chloride, dehydrated with Na2SO4, and distilled to give crude I.

    Abstract: 1427416 2-Benzimidazole carbamic acid esters HOECHST AG 2 Oct 1973 [14 Oct 1972] 45985/73 Heading C2C Alkyl or benzyl esters of 2-benzimidazole carbamic acid or of a 5- and/or 6-substituted 2-benzimidazole carbamic acid or salts thereof, are obtained by converting 2-amino-benzimidazoles with bases to their alkali-metal or alkaline-earth metal salts, reacting these salts with carbonic acid esters in the absence of water and, if desired, converting the salts of 2-benzimidazole carbamates obtained to the free esters by acidification.
