Based on the [hydroxy(4-pyridyl)methyl]phosphonate ligand, three compounds with formula Ni{(4-C(5)H(4)N)CH(OH)PO(3)}(H(2)O) (1), Cd{(4-C(5)H(4)N)CH(OH)PO(3)}(H(2)O) (2), and Gd{(4-C(5)H(4)N)CH(OH)P(OH)O(2)}(3).6H(2)O (3) have been synthesized under hydrothermal conditions. The crystal data for 1 are as follows: orthorhombic, space group Pbca, a = 8.7980(13) A, b =
A novel intermolecular cross-double-Michael addition between nitro and carbonyl activated olefins has been developed through Lewis base catalysis. The reaction took place with a large group of beta-alkyl nitroalkenes and alpha,beta-unsaturated ketone/esters, producing an allylic nitro compound in good to
The chemistry of organoazides is exceedingly rich, since the azide functionality reacts with electrophiles, nucleophiles, and dipolarophiles, with or without the extrusion of dinitrogen. Common place transformation such as Staudinger reductions or ligations, Cu(I)-catalyzed Huisgen cycloadditions (of the “click” reaction family), Curtius or Schmidt rearrangents, nitrene reactions, or imine formation via aza-Wittig reactions all necessitate organoazide precursors or intermediates
