WebWhile the most reactive Mg was produced using the lithium reduction procedure in the presence of alumina, the presently preferred method is entry 11. Though not as reactive as 10, it is more reproducible. The procedures which do not employ alumina also extend equipment life and are thus safer. [Pg.238] Figure 6. WebAluminum hydrides cause the splitting of the C–O bond and formation of the six-membered O–Al containing ring (13OM5260). Furan enters into the ring-opening reaction ( Eq. 1.59) leading to the η 5 -oxapentadienyl (83CC813). (1.59) The following example combines peripheral and O-coordination, as well as ring-opening.

LiAlH4 is a powerful reducing agent that is commonly used in the laboratory for the reduction of esters, carboxylic acids, and other functional groups. LiH is a less reactive compound and is not as commonly used in chemical reactions. Sponsored by TruthFinder
