TL;DR: In this paper, ring-opening metathesis polymerization (ROMP) polymers bearing imidazole and morpholine functionalities were synthesized using an efficient and inexpensive post-modification procedure.
Abstract: In this study, ring-opening metathesis polymerization (ROMP) polymers bearing imidazole and morpholine functionalities were synthesized using an efficient and inexpensive post-modification procedure. First, dimethyl-5-norbornene-2,3-dicarboxylate was polymerized (M n : 130 kDa, Ð: 1.23) in the presence of Grubbs third-generation catalysts through ROMP reactions. Second, these ROMP polymers were modified using octylamine, 1-(3-aminopropyl)imidazole, and 1-(3-aminopropyl)morpholine in the presence of catalytic amounts of tin(II)hexanoate; Sn(Oct) 2 , titanium(IV)isopropoxide; Ti(O-i-Pr) 4 ; and 1,5,7-triazabicyclo[4.4.0]dec-5-ene. Modified polymers were characterized by 1 H, 13 C NMR, FT-IR, differential scanning calorimetry, thermogravimetric analysis, and gel permeation chromatography. Quantitative conversions were achieved using 1-(3-aminopropyl)imidazole as a modification agent in the presence of 10% Sn(Oct) 2 .

TL;DR: A mixed-valence Cu(I) and Cu(II) coordination polymer with an infinite one-dimensional (1-D) structure, [CuI4CuIII4(Mor-dtc)2(CH3CN)2]n (Mor-Dtc−: morpholine dithiocarbamate), was prepared and st...
Abstract: A novel mixed-valence Cu(I)–Cu(II) coordination polymer with an infinite one-dimensional (1-D) structure, [CuI4CuIII4(Mor-dtc)2(CH3CN)2]n (Mor-dtc−: morpholine dithiocarbamate), was prepared and st...

TL;DR: In this paper, a series of complexes and their modes of coordination were reported for MCF-7 breast cancer cell line and were selective to some extent when compared to the WRL68 normal liver cell line.
Abstract: This paper reported series of complexes and their modes of coordination. The series consist of N,N’,O-donor Schiff base formed by condensation reaction of 2-hydroxyacetophenone with 4-(2-aminoethyl)morpholine. The ligand and complexes were characterized by elemental analysis, FT-IR, NMR and UV/Visible spectroscopy. The complexes showed moderate cytotoxicity mediated on MCF-7 breast cancer cell line and were selective to some extent when compared to the WRL68 normal liver cell line.
