Phosphoramidate and Silyl Amine Mediated Synthesis of Isocyanide Cyclopentadienone Iron Complexes

Helvetica Chimica Acta, EarlyView.
Carbonyl ligands in cyclopentadienone iron complexes are replaced by isocyanide ligands without using free, malodorous isocyanides. The reaction takes place via an Aza‐Wittig‐type reaction starting from primary amines, employing either phosphoramidates or silyl amines as intermediate reagents.

Laser Absorption Shock Tube Study of C1 to C4 n‐Alkyl Formate Pyrolysis

International Journal of Chemical Kinetics, EarlyView.
ABSTRACT n$n$‐Alkyl formates are considered as potential alternative fuels or fuel additives. While their oxidation chemistry has been investigated intensely, their pyrolysis chemistry requires more experimental insights. The present work utilizes shock tube experiments in combination with infrared laser absorption measurements to obtain information ...

Charge Directed Selective Co‐Assembly of Ionic Complementary Peptide Binary Mixtures

Small, EarlyView.
Multi‐component peptide systems enable the development of multi‐functional and tunable materials, yet, controlling the co‐assembly of such complex systems remains challenging. This study demonstrates that rational design of peptide charge distribution, together with controlling parameters (pH, stoichiometry, and concentration), can guide selective co ...
