Screening of chiral Diels-Alder catalysts by mass spectrometric monitoring of the retro reaction [PDF]

, 2007
A rapid screening procedure for the identification of chiral Diels-Alder catalysts by ESI MS was developed. Screening of the retro reaction made it possible to indirectly determine the catalyst’s enantioselectivity for the forward, product-forming ...

Chiral electrode behavior of magneto-electrodeposited Cu-Cu₂O films

Journal of Physics: Conference Series, 2009
Chiral properties were investigated in Cu and Cu2O composite films prepared by magneto-electrodeposition. The Cu-Cu2O films were electrodeposited in a CuSO4 and Na2SO4 aqueous solution under magnetic fields B (2 and 5 T) parallel (+B) or antiparallel (-B) to the faradaic current.

Spin-dependent electrochemistry : enantio-selectivity driven by chiral-induced spin selectivity effect [PDF]

, 2018
Spin-Dependent Electrochemistry (SDE) is a new paradigm in electrochemistry where the electrochemical response of a chiral electrod vertical bar solution interface is studied as a function of spin-polarized current.

The Origin of Homochirality by Rotational Magnetoelectrochemistry

Magnetochemistry
The origin of homochirality by rotational magnetoelectrochemistry was theoretically examined. Electrochemical reductions in a rotating solution under a static vertical magnetic field were concluded to yield microscopic vortices with L-activity for ...

Chiral‐Encoded Pt‐Ir Surfaces as Apparent Spin Filter for Enhanced Oxygen Reduction

Advanced Science, EarlyView.
The Chiral‐Induced Spin Selectivity (CISS) effect is employed in chiral‐encoded mesoporous Platinum‐Iridium (Pt‐Ir) electrocatalysts to enhance the oxygen reduction reaction (ORR). A break in spin symmetry leads to a substantial antagonistic difference in activity (>200%) when comparing two enantiomorphs of the same electrode.

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

Chemistry – A European Journal, EarlyView.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.
