Reactions at the alpha carbon
WebThe reaction of alpha-pinene oxidation was carried out in a three-necked flask placed in an oil bath with a bubbler and a reflux condenser (CHEMLAND, Stargard, Poland). Oxygen with a purity of 99.99% was fed from the cylinder through the mass flow meter, and the oxygen flow rate was 40 mL/min. WebThis carbon right here is the alpha carbon. And in order to have an E2 reaction in this case, when we did the video on E2 reactions, but actually, the rule will hold as well for E1 reactions. But in order to have the E2 reaction, …
