Establishing unprecedented types of bonding interactions is one the fundamental challenges in synthetic chemistry, paving way to new (electronic) structures, physicochemical properties, and reactivity. In this context, unsupported element-element are particularly noteworthy since they offer pristine scientific information about newly identified structural motif. Here we report synthesis, isolation, full characterization heterobimetallic Bi/Pt compound [Pt(PCy

Abstract Whereas indications of radical reactivity in bismuth compounds can be traced back to the 19 th century, preparation and characterization both transient persistent bismuth‐radical species has only been established recent decades. These advancements led emergence field chemistry, mirroring progress seen for other main‐group elements. The seminal fundamental studies this area have ultimately paved way development catalytic methodologies involving intermediates, a promising approach that remains largely untapped broad landscape synthetic organic chemistry. In review, we delve into milestones eventually present state‐of‐the‐art Our focus aims at outlining intrinsic discoveries inorganic/organometallic chemistry contextualizing their practical applications synthesis catalysis.

The reactivity of a literature-known, ring-strained cationic bismuth amide toward the unsaturated substrates RN═C═NR, CS2, and acrylonitrile is reported (R = iPr, Cy, pTol). Subtle changes in polarity reaction medium (THF vs pyridine) can be exploited to selectively address two different pathways. Either dinuclear nature starting material preserved, only one substrate molecule per atoms incorporated into product, an aryl migration possible or well-defined mononuclear compounds with Bi/substrate ration 1:1 are observed. These findings correlate unexpected increase species, when solvent increased from THF pyridine, likely connected nuclearity material.

18-membered diazomacrocycles with imidazole or 4-methylimidazole residue as a part of macrocycle were used chromoionophores in bismuth(III) and lead(II) dual selective optodes for the first time. Cellulose triacetate membranes doped macrocyclic are color change from orange/red to different shades blue violet, respectively. Results obtained model real samples showed that easily accessible regenerable sensor materials can be spectrophotometric colorimetric detection determination lead(II). The LOD values 1.63×10-7 M 3.03×10-7 detection, respectively, when using optode residue. For sensing material macroring lowest limits lead(II): 2.14×10-7 3.99×10-7 digital analysis mode,
