Dinuclear Rhodium(I)–N‐Heterocyclic Carbene Complexes as Alkyne Hydropyridonation Catalysts
European Journal of Inorganic Chemistry, EarlyView.Catalyst Improvement by NHC tuning: A series of new RhI–NHC dinuclear complexes has been revealed as efficient alkyne hydropyridonation catalysts. 333053IMes complex displays the highest reactivity of the series, suggesting that a moderate steric demand combined with balanced σ‐donation facilitates precatalyst activation and substrate exchange.

, 1978 The 1/1 reaction of (2-Me{2}NCH{2}C{6}H{4}){4}M{2}Li{2} (M = Cu or Au) with (CO){2}ClRh-dimer affords (2-Me{2}NCH{2}C{6}H{4}M){n} and the novel 2-Me{2}NCH{2}C{6}H{4}Rh(CO){2}. In contrast, the reaction of (x-tolyl){4}M{2}Li{2} (x = 2, M = Cu or Au) under a CO atmosphere results in the formation of ditolyl ketone bitolyl in 69, 92 and 31, 4% yield ...

Rigid Ligand Environments at Beryllium, From Spectroscopic Probes to Small Molecule Activation
European Journal of Inorganic Chemistry, EarlyView.Due to the high rigidity and definition of beryllium scorpionate complexes, they can be used to study metal‐pseudohalide and ‐carbon bonds in detail. Furthermore, these compounds can be used to activate small molecules and exhibit unprecedented transmetalation reactions. In beryllium scorpionate complexes, three of the four available coordination sites

European Journal of Organic Chemistry, EarlyView.A multicomponent carbonylative Suzuki–Miyaura reaction was developed for the synthesis of C‐acyl glycosides. Using Pyridine‐Enhanced Precatalyst Preparation, Stabilization, and Initiation (PEPPSI‐IPr) catalysis and Mo(CO)6 as a solid CO source, the reaction enables selective carbonylation of three components in synthetically useful yields, providing a ...

Helvetica Chimica Acta, EarlyView.A Pd(II) allyl‐amidinate complex catalyzes the selective oxidation of benzyl alcohols to aldehydes using allyl alkyl carbonates as tailored, mild oxidants. The carbonate reagent acts both as oxidant and in situ base, enabling chemoselective conversion and minimizing overoxidation under mild conditions.
