In the crystal structure of the title compound, [Cd(NCS)2(C9H13N)2] n , the Cd(II) cations are coordinated in a slightly distorted octa-hedral geometry by one 3-tert-butyl-pyridine ligand, one 4-tert-butyl-pyridine ligand and two pairs of translationally-equivalent μ-1,3-bridging thio-cyanate ligands, all of which are in general positions. These μ-1,3-bridging thio-cyante anions bridge the Cd(I...
Lithium cadmates bearing different ligands were compared with efficient (TMP)(3)CdLi (TMP = 2,2,6,6-tetramethylpiperidino) for their ability to deprotometalate anisole. The generated arylcadmates were evidenced using I(2). The results show that it is possible to replace only one of the TMP (with a piperidino, a diisopropylamino, a butyl, or a sec-butyl) without important yield drop. In the ligh...
Homogeneous linear poly(tartrate ester) ligands provide high chemical yields and enantiomeric excesses in the epoxidation of trans-hex-2-en-1-ol using Ti(OPr)4-tert-butyl hydroperoxide. Branched poly(tartrate ester) can be use as heterogeneous ligands in the epoxidation of trans-hex-2-en-1-ol using Ti(OPr)4-tert-butyl hydroperoxide. Removal and recovery of the polymer catalyst is a simple filtr...
In the crystal structure of the title salt, C(10)H(16)N(+)·ClO(4) (-), the 4-butyl-anilinium cation is mirror symmetric, the butyl C atoms and anilinium N atom and 1,4-position C atoms of the benzene ring being located on the mirror plane; the perchlorate anion is also mirror symmetric, with two O atoms and one Cl atom lying on the mirror plane. Trifurcated N-H⋯O hydrogen bonding is observed be...
2,4-Di-tert-butyl-6-[1-(3,5-di-tert-butyl-2-hydroxyphenyl)ethyl]phenyl 4-methylbenzenesulfonate
The title compound, C(37)H(52)O(4)S, was obtained by the reaction of 6,6'-(ethane-1,1-di-yl)bis-(2,4-di-tert-butyl-phenol) and 4-methyl-benzene-1-sulfonyl chloride. The mol-ecular conformation is stabilized by an intra-molecular O-H⋯O hydrogen bond. Two of the tert-butyl groups are disordered over two sets of sites with occupancies 0.530 (15)/0.470 (15) and 0.615 (11)/0.385 (11).
The binding of n-butyl isocyanide to human hemoglobin has been examined by means of rapid mixing and chemical relaxation kinetics. It is seen that an extended Adair scheme (ADAIR, G. S. (1925) .I. BioZ. Chem. 63, 529) can be applied to describe the kinetic data. Two relaxation processes are observed which are attributed to binding of ligand to the LY and /3 subunits. The effect of temperature o...
In the mol-ecule of the title compund [systematic name: N-butyl-N-ethyl-2,5,6-trimethyl-7-(2,4,6-trimethyl-phen-yl)-7H-pyrrolo[2,3-d]pyrimidin-4-amine], C(24)H(34)N(4), the pyrrolopy-rimidine ring system is nearly planar, its five- and six-membered rings forming a dihedral angle of 5.3 (2)°. The benzene ring is nearly orthogonal to the central ring system. The N atom carrying the ethyl and n-bu...
The carbon dots were prepared by the microwave method, and then TiO2 doped with was successfully synthesized hydrothermal method. Its structure investigated using TEM, XRD XPS. catalyst applied to degradation of lignin base solution (50 mg in 30 mL sodium hydroxide pH = 12) under ultraviolet light. It found that when mass ratio point 1.5:1, dosage 0.75 g/L, time 6 h, rate could reach more than ...
We report the behaviour of thermoresponsive block copolymers of n-butyl acrylate and N-alkyl acrylamides in [C2mim][NTf2]. Poly(N-isopropylacrylamide) exhibits an upper critical solution temperature in [C2mim][NTf2] whereas poly(n-butyl acrylate) has a lower critical solution temperature. Consequently, these polymers exhibit double thermo-responsiveness correlated with the macromolecular struct...
A four-electron-reduced ruthenium(ii) NADH-type complex, [Ru(bbnpH4)(CO)2Cl](PF6) (bbnpH4 = 2,2'-(4-(tert-butyl)pyridine-2,6-diyl)bis(5,10-dihydrobenzo[b][1,5]naphthyridine)), has been successfully synthesized by mixing an NAD+-type ligand, bbnp (bbnp = 2,2'-(4-(tert-butyl)pyridine-2,6-diyl)bis(benzo[b][1,5]naphthyridine)), and [Ru(CO)2Cl2] under moderate water-gas-shift reaction conditions, wh...
