In Situ Formation

We describe a practical, one step, room temperature in situ synthesis of luminescent CdSe QDs using a bile salt derived metallogel, followed by their isolation from the gel and re-dispersion in an organic solvent.

One Step

Oxygenative cleavage of an inert CAr–NH2 bond with concomitant 1,2 amine migration in 8-aminoquinoline derivatives is achieved through an efficient, catalyst free, one step synthesis of 8-benzyloxy, 7-aminoquinoline directly from 8-aminoquinoline in water at room temperature.
