FeCl 3 and NOBF 4 have been successfully tested as chemical oxidants to promote the polymerization of thiophene-or pyrrole-modified chiral cobalt salen complexes. The iron oxidation procedure particularly delivered an insoluble polymeric species in nearly quantitative yield that was tested for its propensity to promote the dynamic hydrolytic kinetic resolution of epibromohydrin. This catalyst allowed the synthesis of the expected diol in high yield and up to 85% ee. As an insoluble powder, it was either efficiently recycled in a batch reactor via simple filtration or dispersed in a silica support and reused in a flow procedure for up to five cycles. A copolymerization strategy delivered an even more reliable polymerized complex that was repetitively used without showing any loss in activity or in enantioselectivity for five reuses in this transformation.

“…A recent literature survey revealed that the 1,3, 4-thiadiazole derivatives have been widely used by the medicinal chemist in the past to explore its biological activities [6,7] . On the other side, they find increasing application as superconductors [8,9] , optoelectronics [10] , non-linear optical chromophores [11] . Besides, their pharmacological profiles as antifungal [12] , antiproliferative [13] and antioxidant [14] agents have led to an enduring interest in the development of various methods for their synthesis.…”

Reaction of 5-pentadecyl-1,3,4-thiadiazol-2-amine 2 with ethyl cyanoacetate gave 2-cyano-N-(5-pentadecyl-1,3,4-thiadiazol-2-yl)acetamide 3 which was used to synthesize different heterocyclic derivatives comprising coumarin, pyrazole, thiazole, pyridine, pyrimidine, and thiophene rings. Propoxylation of these compounds by using 5 moles of propylene oxide to produce nonionic surface active agents. Antimicrobial and the surface activities were evaluated.
