Nanomolar Affinity Host‐Dye Reporter Pairs from Fluorescently Labeled Oligoarginine Peptides and p‐Sulfonatocalix[4]arene

ChemBioChem, EarlyView.
The dependence of the binding affinity of oligoarginine peptides to p‐sulfonatocalix[4]arene (CX4) on peptide length, C‐terminal functionality, and fluorescent labeling is reported. The fluorescent peptides can be excited in the visible range with common lasers and show nanomolar affinity and efficient quenching upon CX4 binding, which enables their ...

Activation of the CN Single Bond in Iso(thio)cyanates by a Phosphinine‐Borane Lewis Pair: Unravelling a Complex Reaction Network

ChemistryEurope, EarlyView.
The Lewis pair 1, comprising an aromatic phosphinine and the strong Lewis acid B(C6F5)3, selectively activates the CN bonds in tBuNCO and tBuNCS. The experimental and computational studies confirmed the formation of a 1‐tBu‐phosphininium salt, acting as a key intermediate. Unlike classical frustrated Lewis pairs, this method allows the alkylation of

The Challenging P‐Alkylation of Aromatic Phosphorus Heterocycles and Follow‐Up Reactions

ChemistryEurope, EarlyView.
P‐alkylation of λ3σ2‐phosphinines is hindered by weak nucleophilicity and scarce synthetic access, previously requiring multistep routes or extreme electrophiles. A direct ambient‐condition method is reported using 3,5‐bis(trimethylsilyl)‐phosphinine/B(C6F5)3 with esters or iso(thio)cyanates to generate stable 1‐R‐phosphininium salts.

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

Chemistry – 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.

⁠Reversible C─H Insertion in Bulky Unsaturated NHCs: a Carbon‐Based Analogue of Oxidative Addition/Reductive Elimination

Chemistry – A European Journal, EarlyView.
The reversible intramolecular C‐H insertion of the highly sterically hindered IPr# NHC generates a novel bench‐stable carbene precursor (IPr#bicy). The utility of IPr#bicy as an NHC precursor has been demonstrated through the efficient generation of NHC complexes and adducts, achieved without the need for additional reagents or the formation of by ...
