A novel setup to analyze the heat of reaction of different single- and multiphase reactions carried out in continuous flow is presented. The measurement principle of the calorimetric system is based on true heat flow measurements and therefore ensure

Perchloric acid appears unique in its ability to catalyze stereoselective trans-acetalizations of steroids. However, the requisite recipes result in an intermediate phase enriched in perchlorate and organic material with the potential for catastrophi
