چکیده | ||
Red pine leafs were applied for the green method preparation of MgO nano-plates. The MgO nano-plates were used for the one-pot synthesis of dihydropyrano [3,2-c] chromene derivatives. This procedure is very simple and affords excellent yields. MgO nanoplates were synthesized via a simple precipitation method with the using of an extract solution of red pine leaves. The XRD pattern shows a cubic phase ofMgO . Field Emission Scanning Electronic Microscopy (FE-SEM) shows clearly that the surface of the as-prepared MgO nano-plates have a homogeneous microstructure made up of layers of various sizes and forms. The plates form irregular grains with a lateral size of 40-110 nm. | ||
