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.

Chemistry – A European Journal, EarlyView.The synthesis of 2‐methyl propellane and its conversion to various 1,2‐ and 1,2,3‐di‐ and trisubstituted bicyclopentanes is reported. Abstract Bicyclo[1.1.1]pentanes (BCPs) have emerged as isosteric replacements for mono‐ and para‐substituted benzene rings in medicinal and materials applications, involving substitution at the BCP bridgehead (1,3 ...

Chemistry – A European Journal, EarlyView.Three 2‐phosphinophenylaluminum dichloride complexes were synthesized and characterized as novel intramolecular FLPs. These FLP systems exhibit high Lewis acidity and effectively activate challenging substrates including aliphatic ketones, imines, and esters. DFT analysis revealed that strain release and Al–P dynamics govern their reactivity. Abstract (

Chemistry – A European Journal, EarlyView.Copper(I) hydride complexes often exhibit diverse aggregation behavior that can profoundly influence their structure and reactivity. In this study we use a combined experimental and computational approach to identify key structural an electronic factors that govern aggregation in PNNP dicopperhydride complexes.

Distinct Ligand‐ and Metal‐Centered Phosphorescence in a Terbium Carbazolyl Complex
Chemistry – A European Journal, EarlyView.Terbium and lanthanum carbazolide complexes show two distinct modes of luminescence: Strongly temperature‐dependent narrow‐line terbium emission could be induced. In addition, both the terbium and the lanthanum complexes show broad‐line interligand emission processes with excited states of microsecond life‐time.
