2H-3, 1-Benzoxazine derivatives were synthesized by cyclocondensation of 5-nitro-2-cyanoaniline with relative ketone or aldehyde with ZnCl2 as a catalyst. This
A new complex of bis(N-benzyl benzotriazole-N3) dichloro Co(Ⅱ) (Co(Ⅱ)L2Cl2) was synthesized and its crystal was characterized. The interaction of this new com
