Easier, Safer, and Greener: Unlocking the Power of Solid Reagents in Organic Reactions by Mechanochemistry

open access: yesChemistryEurope, EarlyView.
This review highlights the powerful synergy between mechanochemistry and solid reagents to replace hazardous substances traditionally used in organic synthesis. Such an approach offers a safer and more sustainable pathway for conducting organic reactions, with potential benefits in both reactivity and selectivity. The use of solid bases, acids, and gas

Ring‐opening metathesis polymerization‐Derived Organoborane Polymers as Strong Lewis Acids and Luminescent Materials

open access: yesChemistryEurope, EarlyView.
Ring‐opening metathesis polymerization offers access to borane polymers with tunable Lewis acidity, environmental stability, and luminescence. The Lewis acid strength approaches that of B(C6F5)3 when R = Cl and Ar = C6F5, high stability is ensured with chlorophenyl or naphthyl pendent groups (Ar = ClPh, Np), and strong emission is achieved with a ...

ON THE PECULIARITIES OF THE RING CONTRACTION REACTIONS OF HOMODRIMANES VIA ACID MEDIATED EPOXIDE REARRANGEMENT [PDF]

open access: yesChemistry Journal of Moldova: General, Industrial and Ecological Chemistry, 2011
A selective rearrangement of a epoxy-homodrimanic substrate is described. Using fluorosulfonic acid at low temperature leads by ring contraction to a perhydrindanic structure. On the contrary, using boron trifluoride-diethyl ether at r.t.

Total Synthesis and Complete Stereochemical Assignment of Amphirionin‐5, a Potent Natural Osteoblasts Proliferator

open access: yesChemistryEurope, EarlyView.
The convergent total synthesis of a candidate diastereomer of amphirionin‐5 was accomplished in 22 steps via the coupling of the C1‐C16 enone segment and the C17‐C28 aldehyde segment using Stetter reaction. The overall stereochemistry of amphirionin‐5 was fully assigned, based on the comparison of spectroscopic and chiroptical data between the ...

A Review on Applications and Challenges of Fullerenes in Proton Exchange Membranes

open access: yesCarbon Energy, EarlyView.
This review is devoted to the analysis of the use of fullerenes and their functionalized derivatives to improve the efficiency of proton exchange membranes. The synthetic methods, structure, properties, and proton transfer mechanisms of fullerene‐containing membranes are discussed in detail. Promising areas of scientific research are discussed, and key

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

open access: yesChemistry – A European Journal, EarlyView.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.
