It has also been tested whether this approach could work for the synthesis of the beta-lactam antibiotic amoxicillin.46 First, a number of organic and inorganic counter ions were tested to see whether insoluble salts were formed. From this screening, it was observed that zinc significantly decrease ...

... not. The latter turned out to be the case, as small amounts of K2[HgSe2]·H2O (4) emerged from the experiment upon addition of 0.5 vol% of water to the reaction mixture. Complete absence of water, or other volume ratios than 995 : 5 led to no or lower yields. For us, such hydrate compounds are partic ...

... • Aryl alkyl selenides are preparable either (as above) from electrophilic selenium reagents and carbon ncleophiles or from nucleophilic selenium reagents, e.g. ArSe-Na+, and carbon electrophiles. On oxidation they give selenoxides; if these contain a -hydrogen, they may undergo spontaneous syn-add ...
