Benzylation of hydroxy groups with tertiary amine as a base

Methalloporphirins Catalyze Regio and Chemoselective Silylation of Hydroxy Groups with Hexamethyldisilazane (HMDS)

Metalloporphirins; Cu(TPP), Mn(TPP)Cl, CO(TPP), Fe(TPP)Cl, zn(TPP) and Mn(OBP)Cl catalyze region and chemoselective silylation of hydroxyl groups with HMDS. Fe(TPP)Cl is the most effective catalyst and silylation occurs immediately in its presence at room temperature.

Dehydrogenation of a tertiary amine-borane by a rhenium complex.

Photolysis of CpRe(CO)3 in the presence of H3BNEt3 yields the trans-CpRe(CO)2(H)2 complex. This preliminary finding presents a rare example of transition metal mediated dehydrogenation of a tertiary amine-borane and suggests that the abstracted hydrogens may be stored in the form of metal hydride complexes.

An Investigation on Corrosion and Stress Corrosion Cracking initiation of a Ferritic Stainless Steel in a Tertiary Amine Solution

The present study focused on stress corrosion cracking (SCC) and corrosion behavior of ferritic stainless steel (grade 430) in activated methyl diethanolamine (aMDEA) solution, which is classified as a tertiary amine. In this regard, cyclic polarization and U-bend tests were performed in CO2 loaded aMDEA with different concentrations at 25 and 70 °C to observe corrosion behavior and ...

Realization of a Certain Class of Semi-Groups as Value Semi-Groups of Valuations

The pelationship between ABO blood groups and Rh factor with dental caries in soldiers of a military base in Kerman

The aim of this study was to investigate relationship between the ABO blood groups,Rh factor with prevalence of dental caries.data on blood group and dental caries prevalence were collected from 457 soldiers of 05 military base in Kerman.the mean (SD) age of soldiers was 19(1) years.the overall mean and SD of decayed,missing and filled teeth (DMF index) was 4.3(3.2) the mean value for DMF index...
