Novel boronium salt exhibits substantial antibacterial activity when compared to a commercial quaternary ammonium disinfectant

Commercial disinfectants are routinely used to decontaminate surfaces where microbes are expected and unwelcome. Several disinfectants contain quaternary ammonium salts, or “quats”, all being derived from ammonium. Quaternary alkyl dimethyl benzyl ammonium chloride or bromide disinfectants are widely available. These compounds are effective in reducing or eliminating bacteria on contaminated nonporous surfaces. A unique benzyl derived boronium salt with strong detergent action has been developed. It demonstrated 4-8X greater antibacterial activity against 3 different bacteria when compared to an equal concentration of a commercial quant disinfectant solution containing alkyl dimethyl benzyl ammonium chloride and alkyl dimethyl ethylbenzyl ammonium chloride. Antibacterial effectiveness of each agent was determined by the minimum inhibitory concentration (MIC) method.

A general approach for the synthesis of covalent and ionic amine borane complexes containing trinitromethyl fragments has been developed through metathesis reactions between amine chloroborane complexes and potassium salt of trinitromethyl (K[C(NO2)3]). Five covalent and ionic trinitromethyl amine borane complexes have been synthesized in good yields with high purity and it is found that the ionic complex, [H2B(NH3)2][C(NO2)3], might be a promising energetic material on the basis of the investigation of its thermal decomposition behaviour.

One aspect of the present invention relates to "boronium" ions that are stable, hydrophobic, room-temperature ionic liquids. In certain embodiments, ionic liquids of the instant invention are represented by the formula [XnBY4-n]+(n-1) (n-l)Z-1, wherein X refers to a Lewis base, Y refers to a substituent covalently bonded to boron, Z-1 is a charge diffuse anion, and x is 2, 3 or 4. In certain embodiments, the ionic liquids of the instant invention are of the general type [X2BY2]+1 Tf2N-1, wherein each X is independently a tertiary amine, a N-alkylimidazole or a pyridine; and each B-X bond is a B-N bond.

The rates of solvolysis of trimethylamine-monohaloboranes in aqueous dioxane at 25° increase in the series (CH3)3NBH2Cl 3)3NBH2Br 3)3NBH2I. The diiodoborane adduct reacts more slowly than the monoiodo compound but faster than trimethylamine-borane. Only a very slight retardation in rate is observed on substitution of deuterium for hydrogen on boron in the diiodo derivative (kH/kD = 1.1); however, a noticeable solvent isotope effect (kH2O/kD2O = 1.8) is observed for hydrolysis of both the mono- and diiodoborane adducts in 67% aqueous dioxane at 25°. Rates increase with increasing water content of the aqueous dioxane solvent system. No significant effect on rate of acidity is seen for hydrogen ion concentrations as high as 0.3 M or hydroxide ion concentrations up to 0.1 M, nor is the rate appreciably affected by the addition of potassium chloride or potassium iodide up to 0.3 M. The results indicate a mechanism for hydrolysis of the halo compounds quite different from that postulated for amine-BH3 adducts. It is proposed that a rate-determining cleavage of a boron-halogen bond is followed by rapid collapse of an incipient boron(1+) ion. An analogy to nucleophilic substitution reactions in haloborane-amines leading to kinetically stable boronium ions is suggested.
