Recent Advances in Ene Reactions with Carbon Enophiles

Advanced Synthesis &Catalysis, EarlyView.
Recent advances in the classical intra‐ and intermolecular ene nexus with carbon enophiles (alkenes, alkynes, arynes, and allenes) show a considerable increase in structural complexity and an enormous potential for functional applications in polymer science.

A Mild and Efficient Iridium‐Catalyzed Method for Aldimine Hydrogenation

Advanced Synthesis &Catalysis, EarlyView.
A mild, efficient, and broadly applicable iridium‐catalyzed method for aldimine hydrogenation, facilitating access to an array of corresponding amine products in high isolated yields is reported. The developed methodology employs a bidentate iridium‐N‐heterocyclic carbene‐phosphine complex for use at low catalyst loadings, and proceeds under an ...

First‐Principles Investigation of the T‐ and M‐Centers in Silicon Using Meta‐GGA Functionals

Advanced Theory and Simulations, EarlyView.
The relaxed structure for (a) T‐center and (b) M‐center. The calculations on the T‐center demonstrate excellent agreement with the HSE06, reinforcing the efficiency of meta‐GGA approaches for accurate defect characterization in Si. The M‐center is introduced, revealing promising quantum optical properties.
