The shift in the dehydration reaction mechanism from E 1cB (Mg-rich catalysts) to E 2 (Al-rich catalysts) was demonstrated by the existence of two different compensation effect lines, and it was attributed to a change of the active site from Mg 2+ O 2− to Al 3+ O 2− and to...
Elimination reactions of primary alcohols occurs by an E2 mechanism in an acid-catalyzed reaction. First, the acid protonates the oxygen of a primary alcohol to give a primary alkyl oxonium ion. Then, water is lost by an E2 mechanism because a primary carbocation is too unstable to form in...

They include (A) a β-hydride elimination from a coordinated alkoxide. This type of mechanism is common for transfer dehydrogenation of alcohols with phosphine-ligated ruthenium(II) catalysts [29,35]. A second possibility (B) is a Shvo-like mechanism wherein the bridging hydroxyl directs the ...

There are two steps in the Grignard reaction mechanism to turn a ketone into alcohol: The electrons on the carbon in the Grignard reagent attacks the carbonyl, forming a new carbon-carbon bond. Water is added, hydrogenating the oxygen and forming the alcohol.Grignard...

of genetic factors influencing AC with genetic risk variants for AUD. Our Mendelian randomization finding suggests that the underlying biological mechanism for heavy AC might also be relevant in the pathophysiology of AUD. Based on these results we further analyzed if AC MRSs can predict AUD risk....
