Treatment of 1-(n-butyl)-3-N-(2-Ar)acetamido-1, 3-imidazolium chloride (Ar=furylmethyl,phenylmethyl) with excess K2CO3 and [PdCl2(L−L)] (L−L=2 PPh3, dppf) afforded orange compounds composition [(1-(n-butyl)-3-N-(2-Ar)acetamido-1,3-imidazol-2-ylidene)]2Pd (Ar=furylmethyl; phenylmethyl). These complexes were characterized by NMR (1H 13C{1H} NMR), IR micro-analysis data. Subsequently, the catalyti...

Submitted for the MAR08 Meeting of The American Physical Society Nanomechanical Measurements on Ultra-thin Poly(n-butyl methacrylate) Films. SHANHONG XU, GREGORY MCKENNA, Texas Tech University, TEXAS TECH UNIVERSITY TEAM — The mechanical properties of ultra-thin poly (n-butyl methacrylate) (PBMA) films were investigated by the novel bubble inflation technique developed in our lab. Creep experim...

α-Glucosidase inhibitors decrease the cleavage- and absorption rate of monosaccharides from complex dietary carbohydrates, and represent therefore an important class of drugs for management of type 2 diabetes. In this study, a defatted ethyl acetate extract of Eremanthus crotonoides leaves with an inhibitory concentration (IC50) of 34.5 μg/mL towards α-glucosidase was investigated by high-resol...

Nitrosomethylalkylamines with chain lengths from C4 (n-butyl-) to OK (n-tetradecyl-) were each administered to three rats at doses equimolar with 12 mg of the butyl compound. All of the compounds administered to rats at this dose, twice a week for 30 weeks, induced tumors in 100% of the animals. Some of the compounds with even-numbered alkyl chains induced bladder tumors, and a connection was s...

Nitrosomethylalkylamines with chain lengths from C4 (n-butyl-) to C14 (n-tetradecyl-) were each administered in three rats at doses equimolar with 12 mg of the butyl compound. All of the compounds administered to rats at this dose, twice a week for 30 weeks, induced tumors in 100% of the animals. Some of the compounds with even-numbered alkyl chains induced bladder tumors, and a connection was ...

In the past [1-3], most frequently used model substrates for the peroxyester reaction included, among others, hydrocarbons containing activated hydrogen atoms, such as, cyclohexene, and ethers, such as, tetrahydrofuran. Peroxyamidate 1 (R = N(CH3)2) of acceptable purity was prepared in molar quantities by an improvement of the procedure reported by Pedersen [4] utilizing the reaction of N,N-dim...

The P atom in the title mol-ecule, C(10)H(23)ClN(3)O(2)P, has a distorted tetra-hedral coordination. In the C(O)NHP(O) unit, which has syn-oriented phosphoryl and N-H groups, the P-N bond of 1.703 (2) Å is longer and the O-P-N angle of 103.86 (7)° is contracted compared with the respective values in the two P(O)NHC(CH(3))(3) units [P-N = 1.632 (2) and 1.624 (2) Å; O-P-N = 116.80 (8) and 115.32 ...

Determination of relative volatilities flavour compounds in hydro-alcoholic solutions is usually performed by time-consuming and costly standard methods such as the Gillespie dynamic recirculation method. This study tested a quick easy method with simple distillation apparatus for measuring empirical volatilities. A total 17 representative apple pear brandies were selected investigated their al...
