The article conveys some information:
A new sym. and flexible primary amide functionalized ligand, 2,2′-(ethane-1,2-diylbis((pyridin-2-ylmethyl)azanediyl))diacetamide (2-BPEG), was synthesized and structurally characterized. Using this multidentate ligand, four novel metal complexes, [Cu(2-BPEG)](ClO4)2·0.5H2O (1), [Zn(2-BPEG)](ClO4)2 (2), [Zn(2-BPEG)](ZnCl4)·H2O (3) and [Cd(2-BPEG)(H2O)](ClO4)2·H2O (4), were synthesized under ambient conditions and characterized by elemental, spectroscopic and thermal anal., and single and powder x-ray diffraction. Complexes 1-3 are hexacoordinated with an N4O2 donor set (provided by the hexadentate 2-BPEG ligand), while complex 4 is heptacoordinated with an addnl. coordinated water mol. In all cases, the 2-BPEG ligand acts as a hexadentate ligand. A change in the starting metal salt gave 2 and 3 with different tetrahedral anions, ClO4- and ZnCl4-, resp. This provided an opportunity to showcase anion-directed supramol. networks for these compounds Compounds 1, 2 and 4 with perchlorate anions show similar and comparable intermol. interactions in their 3-dimensional networks. However, the supramol. self-assembly of 3 is dominated by a variety of intermol. interactions such as C-H···Cl, N-H···Cl, O-H···Cl and C-H···O due to the presence of a tetrachlorozincate(II) ion. Also, the role of weak intermol. interactions in the crystal packing was analyzed and quantified using Hirshfeld surface anal. Also, compound 4 exhibiting an open Lewis acid site is a very efficient and recyclable heterogeneous catalyst for the solvent-free cyanosilylation of various aldehydes with trimethylsilyl cyanide (TMSCN) producing the corresponding trimethylsilyl ether in high yields. After reading the article, we found that the author used 2-Bromoacetamide(cas: 683-57-8SDS of cas: 683-57-8)
2-Bromoacetamide(cas: 683-57-8) can be used in preparation of (2-carbamoylmethoxy-5-chloro-benzyl)-carbamic acid tert-butyl ester. It was aslo used as precursor to dehydropeptidase I inactivator.SDS of cas: 683-57-8
