Novel boron-containing drugs have recently been suggested as a new class of pharmaceuticals. However, the majority of current boron-detection techniques require expensive facilities and/or tedious pretreatment methods. Thus, to develop a novel and convenient detection method for boron-based pharmaceuticals, imine-type boron-chelating-ligands were previously synthesized for use in a fluorescent ...

Boron neutron capture therapy (BNCT) is an effective clinical method in cancer treatment based on fission reactions and nuclear capturing. In this method, use of the best boron-containing agents for boron therapy and boron delivery agent for transfer to the infectious site are the key points for  efficienct treatment. Our research indicated that calcium fructoborate(CF) was the best compound as...

Reversible, heterolytic addition of H2 across an iron-boron bond in a ferraboratrane with formal hydride transfer to the boron gives iron-borohydrido-hydride complexes. These compounds catalyze the hydrogenation of alkenes and alkynes to the respective alkanes. Notably, the boron is capable of acting as a shuttle for hydride transfer to substrates. The results are interesting in the context of ...

One of the radiotherapy has boron neutron capture therapy (BNCT). They may make it easier to kill tumor cells with BNCT. In BNCT, it is important for boron agents, which have high selectively and high accumulation, to be introduced into tumor cells. To date, the main boron compounds used by the clinical study are sodium mercaptododecaborate (BSH) and pboronophenylalanine (BPA). But, there are n...

The elements carbon and boron uniquely form extensive series of compounds with hydrogen; hydrocarbons and boron hydrides. In comparison to carbon, which forms various chainor ring-like structures, boron, an electron deficient element, forms quasi-aromatic clusters architecturally derivable from a twelve-vertex icosahedral unit. Herein, we focus on a comparison of hydrocarbon and boron hydride b...

Brønsted acid HNTf2 (Tf = SO2CF3) mediated dehydrogenative hydride abstraction from (L(1))BH3 () and (L(2))BH3 () (L(1) = IPrCH2 = 1,3-(2,6-di-isopropylphenyl)imidazol-2-methylidene (); L(2) = SIPrCH2 = 1,3-(2,6-di-isopropylphenyl)imidazolidin-2-methylidiene ()) affords thermally stable hydride bridged mono-cationic hydrido boron compounds [{(L(1))BH2}2(μ-H)](NTf2) () and [{(L(2))BH2}2(μ-H)](NT...

Small boron clusters as individual species in the gas phase are reviewed. While the family of known boron compounds is rich and diverse, a large body of hitherto unknown chemistry of boron has been recently identified. Free boron clusters have been recently characterized using photoelectron spectroscopy and ab initio calculations, which have established the planar or quasi-planar shapes of smal...
