Preferred reaction inert solvents include, for example, acetone, benzene, toluene, xylene, o-dichlorobenzene, nitrobenzene, nitromethane, pyridine, dichloromethane, dichloroethane, tetrahydrofuran, dimethylform
A dry toluene or xylene (12.5 mi) solution of the amide 6 (10 mmol) was treated dropwise with POCl3 (20-50 mmol) under nitrogen at rt. The reaction was stirred at rt for 16 hours (alternatively, the POCl3 reaction was warmed to reflux for 3-5 hours) and then the solvents were care...
Reactions were realized at 24 C for 1 h and stopped by adding 2x RNA loading buffer (95% formamide, 1 mM EDTA, 0.025% SDS, 0.025% bromophenol blue, 0.01% xylene cyanol). Samples were heated 5 min at 95 C and analysed on a 7 M urea 15% acrylamide gel further stained with SYBR ...
optionally substituted 5- or 6-membered non-aromatic heterocyclic group as An example of G as a ring is shown in Exhibit 2. Note that when the point of attachment to the G group is shown to be fluid, the G group
Phthalic anhydride of commercially acceptable quality can be recovered from the neat oxidation of liquid o-xylene with air in the presence of the catalysis system provided by cobalt, manganese and bromine conducted in a single step and in the presence of a small amount of benzoic acid to make ...
Upon complete evolution of H2 gas, the resultant slightly cloudy solution was treated with α,α-dichloro-o-xylene (5.2503 g, 0.0299 mol) and stirred at room temperature for 4 h. DMSO (2 mL) was then added to the reaction mixture, and then stirred for 18 h. The reaction mixture was ...
