In the title N-tosyl-acryl-amide compounds, C20H17NO4S, (I), and C23H21NO3S, (II), the conformation about the C=C bond is E. The acryl-amide groups, [-NH-C(=O)-C=C-], are almost planar, with the N-C-C=C torsion angle being -170.18 (14)° in (I) and -168.01 (17)° in (II). In (I), the furan, phenyl and 4-methyl-benzene rings are inclined to the acryl-amide mean plane by 26.47 (11), 69.01 (8) and 8...
The base-catalyzed Michael addition of 2-methyl-acryl-amide to benzotriazole afforded 3-(1H-benzotriazol-1-yl)-2-methyl-propanamide, C10H12N4O (1), in 32% yield in addition to small amounts of isomeric 3-(2H-benzotriazol-2-yl)-2-methyl-propanamide, C10H12N4O (2). In a similar manner, 3-(1H-benzotriazol-1-yl)-N,N-di-methyl-propanamide, C11H14N4O (3), was prepared from benzotriazole and N,N-di-me...
The title compound, C(15)H(24)N(2)O(2), crystallizes with two unique mol-ecules, (I) and (II), in the asymmetric unit, differing in the orientation of the acryloyl units with respect to the piperidine rings. The acryl-amide units are essentially planar in both mol-ecules (r.m.s. deviations = 0.042 and 0.024 Å, respectively), as are the C(3)N chains of the acryloyl units. The carbonyl O atoms of...
The title compound, C24H31NO3 {systematic name: (E)-3-[(1R*,2S*,4aS*,8aR*)-2-(benzo[d][1,3]dioxol-5-yl)-1,2,4a,5,6,7,8,8a-octa-hydro-naphthalen-1-yl]-N-iso-butyl-acryl-amide}, is a natural product isolated from the stem bark of B. obscura. It is composed of an octa-hydro-naphthalene ring system substituted with an essentially planar benzodioxole ring system [r.m.s. deviation = 0.012 Å] and an e...
The mol-ecule of the title compound [systematic name: N-(carbamoylmeth-yl)prop-2-enamide], C(5)H(8)N(2)O(2), which can be radically polymerized to polymers with thermoresponsive behavior in aqueous solution, consists of linked essentially planar acryl-amide and amide segments [maximum deviations = 0.054 (1) and 0.009 (1) Å] with an angle of 81.36 (7)° between their mean planes. In the crystal, ...
* Corresponding Author Email: [email protected] Objective(s): The main aim of current research was to develop a novel magnetically responsive hydrogel by radical polymerization of carboxymethyl cellulose (CMC) on acryl amide (Am) using N,N'-methylene bis acrylamide (MBA) as a crosslinking agent, potassium persulfate (KPS) as a free radical initiator, and magnetic montmorillonite ( mMT)...
A simple and efficient procedure for the synthesis of N-substituted acryl amides has been developed using Na2CO3/SiO2 or NaHSO4/SiO2. smoothly acts as a base in reaction between acryloyl chloride variety amines to obtain their corresponding products good excellent yield. Additionally, NaHSO4/SiO2 catalyzed Ritter nitrile sec-benzylic alcohols give expected amide product. In both reactions, were...
a new simple and reliable method for rapid and selective extraction and determination of trace levels of zn(ii) ion is developed. zn(ii) ions are adsorbed quantitatively during passage of aqueous samples through pet-aa/aam nano fiber modified. almost all matrix elements were found to pass through the nano fiber to drain. modified poly (ethylene terephthalate)-grafted-acrylic acid/acryl amide na...
the nanocomposites of poly (acryl amide-co-acrylic acid) with different contents of naazeolite were prepared using ammonium persulfate as an initiator and n, n′-methylenebisacrylamide as the crosslinker. the morphology was characterized by sem and the structure ofnanocomposite materials was studied with xrd and ft-ir that showed the interaction betweenporous materials and poly (aam-co-aac). the...
In the title compound, C(7)H(14)NO(5)P, the phosphate group displays rotational disorder of three O atoms with an occupancy ratio of 0.832 (6):0.167 (6). The dihedral angle between the acryl-amide group and PO(2) plane of the phosphate group is 75.69 (7)°. In the crystal, inter-molecular N-H⋯O and C-H⋯O hydrogen bonds link the molecules.
