The reaction of (cymene)RuCl2 (1) with PCY3 was investigated using different stoichiometries and reaction conditions. Whereas a mixture of complex 1 and 2 equiv of PCy3 in methanol gave the known adduct [(cymene)Rucl(2)(PCy3)] (3) along with the phosp ...
Continuing modifications of fuels like gasoline should include evaluations of the proposed constituents for their potential to damage environmental resources such as subsurface water supplies. Consequently, we developed a screening model to estimate well w ...
A tinglucal tributyl[4,6-O-bis(t-butyl)silylidene-3-O-tris(isopropyl)silyl]tin 7 and a triflate derived from isolevoglucosenone (1R,4R,5R)-4-benzyloxy-6,8-dioxabicyclo[3.2.1]oct-2-en-2-yl trifluoromethanesulfonate 10 undergo the carbonylative Stille conden ...
The present study investigates the oxidation of methyl tert-butyl ether (MTBE) by conventional ozonation and the advanced oxidation process (AOP) ozone/hydrogen peroxide under drinking water treatment conditions. The major degradation products identified w ...
Recently, the development of micro-scale solid oxide fuel cells (µ-SOFCs) has become a promising research topic in the area of portable energy production. A µ-SOFC system, which can provide 1 to 2 W electrical power under an operating temperature of 550°C ...
The rapid and complete characterization of chemical reaction mechanisms is of the utmost importance in terms of chemical understanding, safety and efficiency. In this presentation a new small volume reaction calorimeter (25-45mL) is described. With this re ...
Epoxidation of (1RS,2SR,3SR,4RS,6RS,7RS,8RS, 12RS, 13RS)-6,13-bis(benzyloxy)-15,16-dioxapentacyclo[10. 2.1.1(4.7).0(2,11).0(3.8)]hexadec-10-en-8-yl-methanol (12) led to the stereoselective formation of (1RS,2RS,3RS,5RS,6SR, 7RS,8RS, 10RS,11SR, 12SR,16SR)-3 ...
Methyl tertiary hexyl ether (MtHxE) and methyl tertiary octyl ether (MtOcE) are currently being developed as replacement oxygenates for methyl tertiary butyl ether (MtBE) in gasoline. As was the case with MtBE, the introduction of these ethers into fuel su ...
Under conditions of kinetic control (-20-degrees-C), the competition between the cheletropic and homocheletropic addition of SO2 to 5,6,7,8-tetramethylidenebicyclo[2.2.2]oct-2-ene 8 was unaffected by a methyl substituent at C(2). However, the latter induce ...
