- Rapid and Ecofriendly Esterification of Alcohols with 2-Acylpyridazinones
-
Atom-economical esterification is of great importance in green chemistry. In this work, we demonstrated the catalyst and additive free esterification of alcohols by their reaction with 2-acyl-4,5-dichloropyridazin-3(2H)- ones without solvent at 100 oC. Aliphatic and aromatic alcohols were converted into the corresponding esters in good to excellent yields. It is noteworthy that the reaction is solvent-free, atom-economic, easy-workup, and rapid and that the process is inexpensive.

Efficient and green esterification is of great importance. In this work, we demonstrate the catalyst-free esterification of alcohols by their reaction with 2-acyl-4,5-dichloropyridazin-3(2H)-ones under microwave irradiation. Aliphatic and aromatic alcohols were converted into the corresponding esters in good to excellent yields under microwave irradiation in solvent or solvent-free conditions. It is noteworthy that the reaction is catalyst-free, atom-economic, and rapid and that the process is inexpensive.

- NHC-iron-catalyzed aerobic oxidative aromatic esterification of aldehydes using boronic acids
-
(Figure presented) NHC-iron complexes prepared in situ very efficiently afforded benzoates via the aerobic oxidative aromatic esterification of aldehydes with boronic acids. This method uses equimolar amounts of both the aldehyde and the boronic acid allo

- Microwave-assisted acylation of amines, alcohols, and phenols by the use of Solid-Supported Reagents (SSRs)
-
A microwave-assisted synthesis of solid-supported reagents for the acylation of amines has been developed, and the same methodology has been successfully applied to the preparation of acylating agents anchored on different solid supports. Similarly, alcohols, phenols, and thiophenols have been easily acylated using these reagents under microwave irradiation.

- Electrochemical generation and reactions of acyloxytriphenylphosphonium ions
-
Constant-current electrolysis, in an undivided cell, of Ph3P in the presence of a carboxylic acid in CH2Cl2 containing 2,6-lutidinium perchlorate as the supporting electrolyte was shown to generate the corresponding acyloxyphosphonium ion, Ph3P+-OCOR, which was converted in situ to esters, amides, and β-lactams under mild conditions.
