Lithium aluminum amides [LiAl(NHR)4], 6a-6d, easily prepared in Et2O or THF from 1 equiv of LiAlH4 and 5 equiv of amine, proved to be efficient reagents for the synthesis of secondary amides from esters (approximately 100% with unhindered amines and 92% with tBuNH2). They also open aryl epoxides with very high regioselectivity to give 97-98% of the beta-amino-alpha-arylethanols (corresponding to the SN2 mechanism).

A novel metal–organicframework (MOF) [Cu3L(2,6-NDC)2]·0.5DMF (MOF-Cu-1) was synthesized by solvothermal reaction of copper nitrate trihydrate with 2,6-naphthalenedicarboxylic acid (2,6-H2NDC) and amino tridentate N-donor containing ligand of N1-(4-(1H-imidazol-1-yl)benzyl)-N1-(2-aminoethyl)ethane-1,2-diamine (L). MOF-Cu-1 is a three-dimensional (3D) framework with one-dimensional (1D) channels. Because
