Synthesis and Reactions of Ethers

The direct and selective synthesis of phenols from aryl/heteroaryl halides and KOH has been achieved through the use of highly active monophosphine-based catalysts derived from Pd2dba3 and ligands L1 or L2 and the biphasic solvent system 1,4-dioxane/H2O. We have also demonstrated a one-pot method of phenol formation/alkylation for the preparation of alkyl aryl ethers from aryl halides. In many instances, this protocol overcomes limitations in existing Pd-catalyzed coupling reactions of aliphatic alcohols with aryl halides. Finally, we demonstrate that substituted benzofurans can be prepared efficiently via a Pd-catalyzed phenol formation/cyclization protocol starting from 2-chloroaryl alkynes.

Synthesis of Alcohols
Alkenes react with water, in the presence of acid, to yield alcohols. The mechanism follows Markovnikov addition. Alkyl halides react with hydroxide to produce alcohols. Organolithium or Grignard reagents add to aldehydes and ketones to produce alcohols. Hydrogen, from sodium borohydride, lithium aluminum hydride, or hydrogen, adds to aldehydes and ketones to produce alcohols.

Synthesis and Reactions of Ethers
In the Williamson ether synthesis, alkoxide ions react with zero degree or primary alkyl halides to form ethers. Ethers are cleaved with hydrogen halides to form alkyl halides and alcohols. The alkyl group in the alkyl halide is the least hindered alkyl group in the ether.
