The cobalt(II) complexes of D2-symmetric chiral porphyrins, such as 3,5-Di(t)Bu-ChenPhyrin P5, can catalyze asymmetric olefin aziridination with diphenylphosphoryl azide (DPPA) as a nitrene source. Acceptable asymmetric inductions were observed for the [Co(P5)]-based catalytic system, forming the desired N-phosphorus-substituted aziridines in

Acid Halogenation Reagents

Fluoroamidinium salts were an advance in acid halogenation. Compared to chlorides, acid fluorides have greater water stability and a lack of conversion to the corresponding oxazolones upon treatment with organic bases.

Organic Azides and Azide Sources

Since the preparation of the first organic azide, phenyl azide, by Peter Griess in 1864 this energy-rich and versatile class of compounds has enjoyed considerable interest.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
