Organoborane

4-Acetamido-2,2,6,6-tetramethyl-1-oxopiperidinium tetrafluoroborate, most commonly known as Bobbitt's salt, is a cheap and benign oxidant. It’s an oxoamonium salt that is used in oxidative cleveage of C-C and C-O bonds. The most common application of Bobbitt's salts is as a catalyst for the synthesis of dimethylbenzoquinones or DMBQs.

4-Acetamidophenyl boronic acid is a cross-coupling reagent that has been used in the synthesis of a variety of organic molecules. The reaction is stereoselective and proceeds with high yield. 4-Acetamidophenyl boronic acid has also been used to synthesize amides and azobenzenes, which can be substituted with chloride or uv irradiation to give chloroazobenzene or benzotriazole respectively. 4-Acetamidophenyl boronic acid has shown potent inhibition against the enzyme cyclooxygenase 2 (COX2) and acidic hydrolysis.

3-Pyridylboronic acid pinacol ester is a versatile reagent that can be used in the synthesis of polymers with reactive functionalities. This compound is a crosslinker, which means that it reacts with two or more other molecules to form a covalent bond. 3-Pyridylboronic acid pinacol ester has been shown to react with ring-opening methacrylate monomers and expand their polymer backbone, which leads to an increase in the number of reactive groups on the chain. The introduction of 3-pyridylboronic acid pinacol ester can also introduce fluorescent units into polymers for use as probes for biological systems. There are many possible applications for this versatile reagent, including its use in the synthesis of imidazopyridine ligands.
