Gold(I) Phosphine/Phosphido‐Borohydride Complexes

European Journal of Inorganic Chemistry, EarlyView.
Synthesis, structure, and electrochemical characteristics of a homologous series of gold(I) complexes featuring phosphine and phosphido–borohydride ligands. A homologous series of linear, mononuclear gold(I) phosphine/phosphido‐borohydride complexes, encompassing [Au(PR3)2]+ 1, [Au(PR3)(PR2BH3)] 2 and [Au(PR2BH3)2]– 3 (R = tBu, Ad), has been prepared ...

“Naked” Divalent Metal Cations Stabilized by Weakly Coordinating Anions: Syntheses, Properties, and Emerging Applications

European Journal of Inorganic Chemistry, EarlyView.
The preparation of soluble and stable metal M2+ dications only stabilized by weakly coordinating anions, that is, M[WCA]2 salts, is an emerging field that, beyond its fundamental interest, holds promise in reactivity due to the high electrophilicity of the central M2+ center.

Synthesis of a Carbon‐Linked Acyldepsipeptide Derivative

European Journal of Organic Chemistry, EarlyView.
The synthesis of a methylene‐linked acyldepsipeptide (ADEP) is reported. Success relied upon an improve method to generate a versatile vinyl glycine methyl ester synthon and a rationally optimized Grubb’s metathesis. NMR and in silico studies revealed an unusual trans–trans proline orientation for this new unnatural ADEP analog, advancing the ...

Deacylative alkylation (DaA) of N-methyl-3-acetyl-2-oxindole for the synthesis of symmetrically 3,3-disubstituted 2-oxindoles. An access gate to anticancer agents and natural products.

Anais da Academia Brasileira de Ciências
The synthesis of 3,3-disubstituted N-methyloxindoles, starting from 3-acetyl-2-hydroxy-1-methyloxindole employing a sequential one-pot synthesis, is studied. The process involves a first alkylation in the presence of 1 equiv.

Mapping Alkyne Chemical Space—Classifying the Reactivity of Alkynes in Semihydrogenation and beyond Using a Data Science Framework

Helvetica Chimica Acta, EarlyView.
A data science framework integrating DFT featurization and hierarchical clustering was used to map the chemical space of over 2700 alkynes into six subsets before using experimental data for Ni3Zn‐catalyzed semihydrogenation and applying a logistic regression model to categorize substrates by reactivity.

Iconicity as the motivation for morphophonological metathesis and truncation in Nigerian Pidgin

Open Linguistics
We present evidence for iconicity as the motivation for two patterns of morphophonological alternation in Nigerian Pidgin, also known as Naijá. To express an ‘unconventional positive’ in all varieties of Naijá, some nouns with the tone melodies H-L and L-
