Anomeric Amides: Valuable Reagents in Synthetic Organic Chemistry

Angewandte Chemie International Edition, EarlyView.
Enabling late‐stage transformations and skeletal editing, anomeric amides have recently emerged as powerful synthetic tools. Due to their unique properties, anomeric amides have been employed in reactions ranging from amination to halogenation. This minireview provides an overview of recent progress in using anomeric amides across a variety of ...

Surfactant‐Enhanced Electrospun Nanofiber Filters for Efficient Viral and Bacterial Inactivation

Journal of Applied Polymer Science, EarlyView.
In this work, electrospun polyacrylonitrile (PAN) nanofibrous filters functionalized with surfactants (CTAB, CPC, and SDS) were developed for air filtration applications. The PAN nanofiber mats enable efficient particulate matter capture while simultaneously providing antimicrobial and antiviral activity against bacteria (E. coli and S.

A Simple and Efficient Approach to the Synthesis of Endo and Exo Bicyclo[6.1.0]nona-3,5-diene-9-carboxaldehyde

Molecules, 2007
Monobromination of 1,5-cyclooctadiene, followed by cyclopropanation with ethyl diazoacetate, led to the formation of endo and exo ethyl 4,5-dibromobicyclo[6.1.0]nonane-9-carboxylates 3a and 3b. Bis-dehydrobromination of 3a and 3b using 1,8-diazabicyclo[5,

The Challenging P‐Alkylation of Aromatic Phosphorus Heterocycles and Follow‐Up Reactions

ChemistryEurope, EarlyView.
P‐alkylation of λ3σ2‐phosphinines is hindered by weak nucleophilicity and scarce synthetic access, previously requiring multistep routes or extreme electrophiles. A direct ambient‐condition method is reported using 3,5‐bis(trimethylsilyl)‐phosphinine/B(C6F5)3 with esters or iso(thio)cyanates to generate stable 1‐R‐phosphininium salts.

Synthesis and characterization of a pyridinium IL-tagged Schiff base Pd(II)-complex: An efficient catalyst for the Suzuki reaction at room temperature under aerobic conditions

Results in Chemistry
To address some drawbacks associated with the Suzuki reaction herein we report a new pyridinium IL-tagged Schiff base Pd(II)-complex. First pyridinium IL was synthesized and condensed with salicylaldehyde to prepare a new IL-tagged Schiff base which on ...
