A thermally stable cadmium-based chiral metal-organic framework (MOF), {[Cd2(L)(H2O)(DMF)]·3DMF·2H2O}n (1; DMF = N,N-dimethylformamide), has been synthesized from an achiral ligand by spontaneous resolution. The MOF features 1D open channels with a large density of active metal sites and has a 3,6-c binodal net with a rare sit 3,6-conn topology. The metal-bound water and DMF solvents could be easily removed along with the guest molecules in the lattice upon activation to afford the desolvated framework 1′. It exhibits microporous nature, as confirmed by the gas-sorption measurements with carbon dioxide uptake of 43.2 cm3 g-1 at 273 K. The open metal sites in the framework make it an outstanding heterogeneous catalyst in the Strecker reaction for the synthesis of α-aminonitriles in a solvent-free state at room temperature with excellent conversion yields.

Sulfated tungstate: A green catalyst for Strecker reaction
Pathare, Sagar P.,Akamanchi, Krishnacharya G.
experimental part, p. 871 - 875 (2012/03/08)
A straightforward, mild, efficient, and general method has been developed for the synthesis of α-aminonitriles via Strecker reaction starting from aldehydes or ketones, amines, and trimethylsilyl cyanide in the presence of sulfated tungstate as a heterogeneous mild solid acid catalyst at room temperature and solvent free condition. The developed method has been successfully applied for the synthesis of a wide range of α-aminonitriles with variable functionality.

A new N-heterocyclic catalyst system which contains N-heterocyclic carbene and amido as ligands, which are strongly bound to a palladium metal. Another heteroatom functionality can be used as a third ligand L. The NHC-amidate ligand system is unique in structure, and shows excellent reactivities in a number of chemical reactions. The chemical reactions include carbon-carbon and carbon-heteroatom (oxygen and nitrogen) bond formations, and oxidation reactions of saturated carbon chemicals via C—H activation.
Synthesis and reactions of 4-hydroxy-2(1H)-pyridones with thienyl and pyridyl substituents in position 6 starting with azomethines and malonates
Schnell, Barbara
, p. 541 - 548 (2007/10/03)
The reaction of 4 with substituted diethyl malonates 5a, or 'magic malonates' (bis-2,4,6-trichlorophenylmalonates 5b) leads to 4-hydroxy-2(1H)- pyridones 6. The azomethines 4 are prepared via the Strecker compounds 3 starting with methyl ketones 1, anilines, and potassium cyanide. Chlorination of pyridones 6 with sulfuryl chloride leads to compounds 7 while nitration gives 9.
