Allylic alcohols may be derived from alkenes by metallation to give the allylpotassium species, followed by treatment with fluorodimethoxyborane. Oxidation of the resultant boronic ester with hydrogen peroxide gives the allylic alcohol (Scheme 15). 106,107 Some allylic rearrangement may be observed; for example, metallation of α-pinene with potassium t-butoxide in petroleum ether solution and Allylalkohol ist ein wichtiges Zwischenprodukt in zahlreichen organisch-chemischen Synthesen.

Allylalkohol synthese

Allyl Alcohol from Glycerol and Oxalic Acid. A mixture of 500g anhydrous oxalic acid and 500g of glycerol was heated in a partial vacuum on a water bath for 4-5h (or longer) until formic acid ceased to distill over. The mixture was then gradually heated to 240°C under ordinary pressure, the flask being fitted with a fractionating column. We have developed a modular procedure to synthesize allylic alcohols from tertiary, secondary, and primary alkyl halides and alkynes via a Cu-catalyzed hydrocarbonylative coupling and 1,2-reduction tandem sequence. The use of tertiary alkyl halides as electrophiles was found to enable the synthesis of various allylic alcohols bearing α-quaternary carbon centers in good yield with high 1,2 Allylic alcohols represent an important and highly versatile class of chiral building blocks for organic synthesis.

Today allyl alcohol is produced commercially by the Olin and Shell corporations through the hydrolysis of allyl chloride: CH 2 =CHCH 2 Cl + NaOH → CH 2 =CHCH 2 OH + NaCl Allyl alcohol can also be made by the rearrangement of propylene oxide , a reaction that is catalyzed by potassium alum at high temperature.

Eine Alternative zur Ameisensäure ist Oxalsäure; allerdings wird dieses alternative Verfahren nicht empfohlen, da es nicht zu befriedigenden Resultaten führt. The Tsuji–Trost reaction is a palladium-catalysed substitution reaction involving a substrate that contains a leaving group in an allylic position. The palladium catalyst first coordinates with the allyl group and then undergoes oxidative addition, forming the π-allyl complex. This allyl complex can then be attacked by a nucleophile, resulting in the substituted product. This work was first pioneered by Jiro Tsuji in 1965 and, later, adapted by Barry Trost in 1973 with the (R)-Sarkomycin was prepared using a five-step total synthesis. Key steps in the enantioselective construction of the targeted scaffold were a rhodium-catalyzed asymmetric conjugate alkenyl Alexandre Lumbroso, Michael L.
