However, implementing such transformations remains challenging due to the stringent requirements imposed by biocompatibility. To date, Tsuji–Trost allylation has not yet been successfully demonstrated in living cells, and in vivo applications remain unrealized, primarily due to the presumed incompatibility between traditional organic chemistry and the complex aqueous environments of biological systems. Nevertheless, significant progress has been made in this area over the past two decades. The successful execution of a Tsuji–Trost reaction in aqueous media requires careful consideration of several key factors, including the choice of catalyst, ligand, leaving group, and nucleophile, as well as the influence of water on reactivity and selectivity. In this review, we highlight the latest advancements in biocompatible palladium-catalyzed Tsuji–Trost-type reactions, with a particular focus on deprotection and allylation reactions conducted in aqueous environments and in living systems.

For example, hydrogen bonding in amino-functionalized metal–organic frameworks (MOFs) enhances the detection of ammonia, and π–π stacking in phthalocyanine films aids in identifying aromatic volatile organic compounds (VOCs) such as benzene. Open metal sites in frameworks allow electrostatic gas binding, affecting electrical resistance, while perturbing the coordination sphere in porphyrins enables optical sensing. This review encompasses MCC platforms, ranging from Schiff base complexes to 3D MOFs and 2D materials, and highlights their tunable properties for gases such as VOCs, CO₂, SO₂, and CH₄, as well as other gases.

Over time, their potential has expanded beyond photocatalysis, and QDs have increasingly been utilized as catalysts in organic synthesis, offering energy-efficient alternatives to traditional methods. Their size-dependent bandgap and high surface area make them versatile tools for driving chemical reactions in a sustainable manner. Recent studies have also highlighted their ability to mediate single-electron transfer (SET) processes, which enhance both reaction efficiency and selectivity. Moreover, QDs have been incorporated into artificial photosystems, improving charge transfer mechanisms and broadening their catalytic applications.

Ultrasmall AuNPs (uAuNPs), with sizes Ranging from 2 to 5 nm, and gold nanoclusters (AuNCs), with sizes less than 2 nm, are often dealt with interchangeably in the literature, making it challenging to review them separately. Although they are grouped in our discussion, their chemical and physical properties differ significantly, partly due to their electronic properties. The distinct optoelectronic properties of uAuNPs and AuNCs are usually not observed in gold metal and nanoparticles of larger sizes. Since small AuNPs tend to aggregate, several routes have been developed to prevent the formation of larger sizes, such as nucleation within porous materials. Controlling the particle size using synthesis methods is challenging, and uAuNPs and AuNCs can be fabricated simultaneously in the same preparation, necessitating separation and additional laboratory efforts. AuNCs can be stabilized by the prevalent soft ligands, such as phosphine and thiolate, unlike uAuNPs, in which a wide range of ligand sets can be used for stabilization. This review is organized around core sections concerning the synthesis, medical and environmental applications, and calculation studies of uAuNPs. It remains valuable to address the current stimulating market growth and potential market constraints when reviewing the expanding applications of AuNPs in the healthcare sector. A significant proportion of the synthesis processes involve the fabrication of uAuNPs and AuNCs in aqueous solutions. An obvious advantage of this work is that we focus on the medical and environmental applications, which often require water-dispersible nanoparticles. Calculation investigations explain the structural dynamics and importance of fine-tuning the size of uAuNPs to impart distinct properties.
