The mixture was then treated by sonication for about 30 min, giving a clear solution.
In a typical synthesis, 2.6 g of CTAB was added to 100 g of deionized water and stirred to give a clear solution.
He described this poison as 'disappearing in water', giving a clear solution.
The insoluble (I) peptide fractions dissolved readily in acetonitrile which was then diluted 1∶1 with 0.1% aqueous TFA giving a clear solution.
The resulting suspension was allowed to warm to room temperature and diluted with EtOAc (50 mL), giving a clear solution.
After 60 min the reaction was complete by TLC and 1 m triethylammonium bicarbonate (TEAB, 0.5 mL) was added, followed by sufficient CH3CN to give a clear solution.
Samples were dissolved in 3.0 ml A/R Nitric acid containing 10% of 30% hydrogen peroxide solution by microwave digestion at 80 degrees for 1 hour to give a clear solution.
Thus treatment of piperidine with CuMes in THF gave initially a yellow crystalline precipitate, which subsequently dissolved on stirring to give a clear solution from which the desired product copper(I) piperidide (4) was then obtained.
The quantitative H NMR-spectra (not shown) of the two-stage particles were measured in deuterated chloroform which is a good solvent for the both components and gives a clear solution.
