The copper( Ⅱ ) complex, [Cu(oxpn)Cu(tmen)2](ClO4)2 was synthesized, where oxpn is N, N’ -bis ( 3-aminopropyl) oxamido and tmen is N, N, N’ N’ -tetram-ethyl
Since the pioneer work of Keller and Bhasin on the oxidative coupling of methane, many catalyst systems, mostly based on the oxides or complex oxides of alkali
Diaza Crown ethers are versatile complexing reagents, their complexing abilities are dramatically modified by the electron donating atoms on substituents attach
Starch is a granular mixture of nomopolymers of α-D-glucopyranosyl units. These polymer molecules are hydrogen bonded and aligned radially in the granule. Star
