The recently isolated abnormal N-heterocyclic carbene (aNHC) has been established as an efficient organocatalyst in ring opening polymerization of three different cyclic esters rac-lactide (rac-LA), ε-caprolactone (ε-CL), and δ-valerolactone (δ-VL). Preliminary DFT calculations indicate that aNHC can be a better organocatalyst than the corresponding nNHC(More)
The membrane integrity of circulating red blood cells (RBCs) is compromised by the deleterious actions of -radiation in humans. Tea is the most widely consumed popular, inexpensive and non-toxic beverage rich in antioxidants. Here, we explored the radioprotective actions of black tea against the -radiation-induced membrane permeability of human(More)
A series of zinc complexes (1-6) supported by substituted phenalenyl ligands was synthesized by reacting the phenalenyl ligands with diethyl zinc under ethane evolution. The solid state structures of these complexes (1-6) were determined by single crystal X-ray crystallography. Furthermore, the organozinc complexes (4-6) were tested for the polymerization(More)
