The reaction is of very broad scope, and hundreds of alcohols have been prepared in this manner. R may be alkyl or aryl. In many cases the hydrolysis step is carried out with dilute HCl or H2SO4, but this cannot be done for tertiary alcohols in which at least one alkyl group is ...
The authors have reported the synthesis of a skeletally and stereochemically diverse small-molecule col- lection by a DOS approach based around the varied reactivity of densely functionalized chiral amino propargylic alcohols 1a–d (Fig. 4). These could be synthesized as a complete matrix of ster...
For more practice, try working on these examples which require similar reasoning: [more discussion of these problems in Note 2] 4. Meta- Directors From Ortho- , Para- Directors Let’s look at a different type of problem. Below, we have a carboxylic acid (meta- director) para to a nitro...

(2007) demonstrated the highly selective, hydrolysis free O-acylation of alcohols using subcritical water (Scheme 10). Employing a reaction temperature of 200 °C, a pressure of 5 MPa, the acylation of benzyl alcohol 35 was achieved in <10 s, using acetic anhydride 37 as the acylating ...
Incorporation of nitrile groups into fine chemicals is of particular interest through C(sp3)–H bonds activation of alkyl nitriles in the synthetic chemistry due to the highly efficient atom economy. However, the direct α-functionalization of alkyl nitriles is usually limited to its enolate chemist...
Alkynide Synthesis: Study with Video Lessons, Practice Problems & Examples Topic summary Created using AI Inorganic synthesis, starting with a terminal alkyne allows for the formation of an acetylide ion through deprotonation using a strongbaselike NH2-. This ion can then undergo an SN2reactionwith...
Practically, the use of alcohols as solvents has strong reducing properties due to the solvated electrons, and ˙H atoms are produced primary after irradiation process. The reducing radiolytic species yield is less in low dielectric solvents such as THF or propylene glycol monomethyl ether acetate ...
