Abstract: The present invention encompasses structures of the formula I: ##STR1## or the pharmaceutically acceptable non-toxic salts thereof wherein: G represents ##STR2## where Q is aryl substituents optionally mono or disubstituted with hydroxy or halogen;T is halogen, hydrogen, hydroxyl, amino or alkoxy having 1-6 carbon atoms;W is oxygen, nitrogen, sulfur, or optionally substituted methylene;X is hydrogen, hydroxyl, or alkyl;Z is an organic or inorganic substituent optionally forming a ring with subtituents on Q; ##STR3## independently represent optionally substituted carbon chains; wherein k, m, and n are independently 0, or an integer of from 1-3 R.sub.3, R.sub.4, R.sub.5, and R.sub.6 are the same or different and represent organic or inorganic substituents.These compounds are highly selective agonists, antagonists or inverse agonists for GABAa brain receptors or prodrugs of agonists, antagonists or inverse agonists for GABAa brain receptors.

Abstract: A system provides an oxygen-bearing gas and a gaseous reactant stream to a fluidized bed reactor. A sparger causes an entraining of the oxygen bearing gas into the reactant gas stream. A feed line couples the sparger to the reactor's fluidized bed and introduces the reactant gas stream and entrained oxygen-bearing gas directly into contact with the fluidized bed. A controller controls both the amount of oxygen-bearing gas and the gaseous reactant so that, at the point of feed injection, the fluidized bed catalyst does not experience an oxygen deficiency. To assure safety, the reactant content of the combined feed and oxygen stream is maintained above an upper flammability limit, preferably with a safety margin of at least 25%. In one embodiment, the system enables the production of acrylonitriles from a feed stream comprising ammonia, propylene and oxygen.

Abstract: Processes for hydrocyanation of nonconjugated acyclic aliphatic monoolefins, monoolefins conjugated to an ester group, or monoolefins conjugated to a nitrile group which utilize a catalyst precursor composition comprising a bidentate phosphite ligand and zero-valent nickel preferably in the presence of a Lewis acid promoter. Catalyst precursor compositions are also disclosed.
