General one-loop formulas for decay $$h\rightarrow Z\gamma $$ h→Zγ

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
Radiative corrections to the decay $$h\rightarrow Z\gamma $$ h→Zγ are evaluated in the one-loop approximation. The unitary gauge is used. The analytic result is expressed in terms of the Passarino-Veltman functions.

Non-metal-templated approaches to bis(borane) derivatives of macrocyclic dibridgehead diphosphines via alkene metathesis

open access: yesBeilstein Journal of Organic Chemistry, 2018
Two routes to the title compounds are evaluated. First, a ca. 0.01 M CH2Cl2 solution of H3B·P((CH2)6CH=CH2)3 (1·BH3) is treated with 5 mol % of Grubbs' first generation catalyst (0 °C to reflux), followed by H2 (5 bar) and Wilkinson's catalyst (55 °C ...

Practical and Efficient Synthesis of (E)-α,β-Unsaturated Amides Incorporating α-Aminophosphonates via the Horner–Wadsworth–Emmons Reaction

open access: yesMolecules
An efficient and practical procedure for the synthesis of (E)-α,β-unsaturated amides incorporating α-aminophosphonates, derived from readily accessible phosphonoacetamides, via the Horner–Wadsworth–Emmons (HWE) reaction was developed.

Isomerized Conjugated Molecules as Hole‐Selective Contacts for Inverted Perovskite Solar Cells

open access: yesSmall Structures, Volume 6, Issue 12, December 2025.
A BTBT (benzothieno[3,2‐b]benzothiophene) isomeric derivative, (2‐(benzo[b]benzo[4,5]thieno[2,3‐d]thiophen‐4‐yl)ethyl)phosphonic acid (BTBT‐Z), is reported. BTBT‐Z adopts a zig‐zag configuration with a sulfur opposite to the anchoring group. This structure enhances its interaction with the perovskite layer, improving crystallization and thin‐film ...

Synthesis of Diaryl‐ and Dialkynylphosphinates From Ubiquitous PV Sources via a Redox‐Neutral Approach

open access: yesAdvanced Science, Volume 12, Issue 36, September 25, 2025.
Classical strategies for P─C bond formation rely on precursors (e.g., PH3, H2PO2, PCl3) obtained from P4, which is produced via the energy‐intensive thermal process. Here, an alternative, redox‐neutral approach is explored. Primary phosphate sources are activated with triflic anhydride (Tf2O) and 4‐dimethylaminopyridine (DMAP) to a versatile PV ...

Catalysis in Chemical Modification of Proteins

open access: yesChemCatChem, Volume 17, Issue 11, June 6, 2025.
Catalytic principles of synthetic organic chemistry have been increasingly applied to chemical modification of proteins during the recent years. This review article describes how seven types of catalytic systems —electrocatalysis, photocatalysis, metal catalysis, acid catalysis, organocatalysis, supramolecular catalysis, and heterogeneous catalysis ...
