Upon prolonged exposure to atmosphere containing not less than 60 percent relative humidity, the insoluble complex remained visibly dry and free-flowing whereas each starting material under similar exposure exhibited marked hygroscopicity, became distinctly moist and was not a free-flowing granular solid. Two bonds pointing inside both rings in a bicyclic heteroaryl system such as -Y 1n - in structure h - i indicates that the substituents are able to connect to any carbon and nitrogen on both rings that can accept a covalent bond other than hydrogen. At temperatures within this range, there was added to the melted benzophenone complectate When however, there is employed an amino alkanol material containing more than one hydroxyl group, ring closure and resulting formation of a cycliccarbamate may occur between the urea moiety and the amino alkanol moiety involving one, or, as the case may be, the other hydroxyl site. An illustration of the modification of the behavior of salicylic acid which resulted from its complection in the present example, is the difference between complectate and complex in toxicity for numerous microorganisms. This product was analyzed by 1 H- NMR. Water 25mL was added and aqueous layer extracted with ethyl acetate 15mL x 3. The organic layer was washed with water, dried over sodium sulfate, filtered and evaporated. This product was analyzed by 1 H-MR. OP Scheme 2.

This is believed to be explained by the cross-linking at the energy levels characteristic of bonding of the present complexes, by the involvement of the -thiol groups at the extremities of the molecule of the present complectate, with complectate sites variously disposed within the polymeric complectants.
When the stirring was interrupted, briefly, the white precipitate tended to settle in the mixture. The average molecular weight of the polymer was approximatelyas determined by a standard light-scattering method, by ascertaining viscosity of solutions, and, most precisely, by ultracentrifuging. EXAMPLE 5-E Double complex of 2,3-dihydrooxobenziso sulfonazole and his 2-ethylhexyl ester of sodium sulfosuccinate As is more fully set forth hereinafter, the compound 2,3-dihydrooxobenzisosulfonazole and its salts form complexes according to the present invention.

The complexes of the instant subgenus of the present invention will be better understood by referenec to the following examples which represent only a small part of the experimental work carried out, and intended solely to be illustrative but not to define the scope of the present invention.
Suitable solid carriers are magnesium carbonate, magnesium stearate, talc, sugar, lactose, pectin, dextrin, starch, gelatin, tragacanth, methyl cellulose, sodium carboxymethyl cellulose, a low melting wax, cocoa butter, and the like.
The present invention provides compounds of structural formula I or pharmaceutically acceptable salts thereof. An example, for instance, is water or water-propylene glycol solutions for parenteral injection. In preparing the instant complex, separate solutions in xylene are prepared, one containing the monomeric complectate and the other an equirnolecular amount, upon the basis of cyclic carbamate moieties, of polymeric complectant.

|Upon completion of the destrucscattering method, by ascertaining the viscosity of solution of the microorganisms, the water may be passed tions, and, most precisely, by ultracentrifuging.
When polymerization has gone forward to the desired degree, the entire mixture is dispersed slowly and with stirring into Water at approximately room temperature, whereby the dimethylformamide solvent is dispersed as an aqueous solution in which the polymerpolymer complex precipitates. In contrast, the complex prepared according to Example 1-D gave a zone of inhibition of from 1 to 2 millimeters. The oxazolidinone complectant was a liquid and the phenol disappeared in it promptly with resulting formation of a complex.
The spectrum of the resulting preparation indicated the presence of uncompleted phenol, and a complex of 3,5 dimethyloxazolidinone and phenol.

Within this zone, the microorganisms were completely inhibited, but such inhibiting action was clearly confined to the said small zone.
Each of the starting solutions originally is of a viscosity only slightly greater than the viscosity of the solvent. In the present example, Below Schemes 6 - 9 show the application of above synthetic methodologies to synthesize specific compounds of the present invention. For example, at concentrations which might ordinarily be employed inthe sweetening of beverages, solutions of a complex of the sulfonazoloxazolidine type alone are clear at temperature up to about C.

The polymer-monomer complex thus prepared is then gradually warmed in dimethyl formamide solvent. The complex contained approximately The properties of the hydroxy aromatic and sulfhydryl aromatic complexes of the instant invention difiFer from the sum of the properties of the starting materials in that such complex derives its physical properties primarily from the complectant member, and its chemical and particularly biochemical properties primarily from the complectate member.
The rate of such flux can be controlled by either providing a rate controlling membrane or dispersing the active compound in a polymer matrix or gel.
