Yield:-
Reaction Conditions:
with oxygen in acetonitrile; for 12 h;UV-irradiation;
Steps:
2.4. GC/MS analysis
50 mmol NaTTFA in acetonitrile (5 ml) mixed with K7050 (0.4 g/L)were illuminated by UV light (Philips CLEO 75 W) with an intensity of1mW cm- for 12 h in the presence of O2. Afterwards the mixture wasfiltrated in order to remove TiO2. The liquid extract was analyzed byGC/MS using a GCMS-QP5000 (Shimadzu) coupled with an AOC-5000Plus auto sampler and employing parameters based on Method 8270D(SW-846): Semivolatile Organic Compounds by Gas Chromatography/Mass Spectrometry (GC/MS). A capillary RXI-5MS column(30m×0.32 mm, dF=1 μm, Restek) was used to perform the separationprocedure. In a typical analysis 2 μl of the liquid extract wereinjected in a split/splitless injector of the GC/MS system. The columnoven was held at 40 °C for 4 min, followed by an increase in a rate of10 °C/min to reach a final temperature of 270 °C. The temperature ofboth, the injection and the MS interface was adjusted to 280 °C. The MSscanned from 35 m/z to 500 m/z.
