LIBRIUM:
„Yield enhancements, reduction of reaction time, and less racemization were observedunder microwave heating when compared to conventional heating in similar conditions.“
„…using a commercial microwave oven. The advantages of this method include freedom from racemization, minimal activation…“
„Using microwave irradiation no detectable racemization was observed and a consistent reduced reaction time was obtained.“
„The results showed that some advantages, implying less racemization, could be gained by using the microwave technique.“
Zajímavé. Skoro jako kdyby přímá kauzalita nebyla až tak jasná? ;-)
