Abstract:
... In this Article, we expand upon the catalytic hydrothiolation of 1,3-dienes to afford either allylic or homoallylic sulfides with high regiocontrol. Mechanistic studies support a pathway in which regioselectivity is dictated by the choice of counterion associated with the Rh center. Non-coordinating counterions, such as SbF₆–, allow for η⁴-diene coordination to Rh complexes and result in allylic s ...

The performance of the condenser was evaluated by using two common refrigerants namely R12 and R134a to separate the water and essential oil molecules of spearmint (Mentha spicata) leaves from a vapor-air mixture flow. Three levels of air speed (1, 2 and 3 m/s) and temperature (180, 210 and 250 °C) were selected for the va ...
