There are provided novel (2-imidazolin-2-yl) fused heteropyridine compounds, and intermediate compounds for the preparation thereof, and a method for controlling a wide variety of annual and perennial plant species therewith.

(2-imidazolin-2-yl) fused heteropyridine compounds, intermediates for

There are provided certain 13-halo-23-imino-LL-F28249 compounds which are useful for controlling endo- and ectoparasites, insects, acarids and nematodes.

13-halo-23-imino derivatives of LL-F28249 compounds and their use as

Aqueous chemiluminescent systems are found to have improved chemiluminesence due to presence of surfactants in minor amounts.

Enhanced aqueous chemiluminescent systems

N,N'-bis(trifluoromethylsulfonyl)oxamides are described with 2,2,2-trifluoroethyl, (ethoxycarbonyl)methyl, and [(phenylmethoxy)carbonyl]methyl substitution at the amido nitrogen atoms. These compounds, when used in chemiluminescent formulations, furnish superior light capacity and quantum efficiency. Preparation of the compounds and their use for chemiluminescence are described.

Novel N,N'-bis(trifluoromethylsulfonyl)oxamides and chemiluminescent

Quaternary salts of N,N'-bis(morpholinoalkyl)-N,N'-bis(trifluoromethylsulfonyl)oxamides and of N,N'-bis(pyridylalkyl)-N,N'-bis(trifluoromethylsulfonyl)oxamides are useful for generation of chemiluminescence by reaction with hydrogen peroxide in aqueous solvent.

Aqueous chemiluminescent systems

There is provided a process for preparing amides which comprises reacting an amine, or an amide, and an acid halide, or anhydride, in suitable molecular proportions, in an inert organic diluent, in the presence of an effective amount of a molecular sieve, until the reaction is completed, separating the molecular sieve, and recovering the amide from the organic mother liquor.

Process for preparing amides by reaction in presence of molecular sieve

N,N'-bis(trifluoromethylsulfonyl)oxamides are described with a number of variations by substitution at the amido nitrogen atoms. These compounds when used in chemiluminescent formulations will furnish superior light intensity and quantum efficiency. Preparation of compounds and their use for chemiluminescence are described.
