The critical synthetic access to odd-numbered calix[n]arenes has evidently resulted in less attention for these macrocycles, although specific molecular recognition phenomena have been observed for some of them. A straightforward fragment coupling approac

Alkoxy substituted 1,2,4-triazolo[1,5-c]-pyrimidine-2-sulfonamides are prepared from alkoxy substituted 1,2,4-triazolo[1,5-c]pyrimidine-2-sulfonyl halides by condensation with substituted N-trialkylsilylanilines and by other methods. N-(2,6-dichloro-3-methylphenyl)-5,7-dimethoxy-1,2,4-triazolo[1,5-c]pyrimidine-2-sulfonamide is typical. The compounds are general and selective pre- and postemergence herbicides.
