Photoreaction of Oxalyl Chloride with Cyclohexene

Reactions of oxalyl chloride with 1,2-cycloalkanediols in the presence of triethylamine.

The relationship between the product patterns and the configurations of 1,2-cycloheptane- and 1,2-cyclooctanediols 9 in the cyclocondensations with oxalyl chloride in the presence of triethylamine at 0 degrees C has been shown analogous to that obtained for 1,2-disubstituted acyclic ethylene glycols 1: cis-1,2-cyclooctanediol (9f) produced the cyclic oxalate 14f as the major product, while tran...

Application of Green Procedure for the Synthesis of Substituted Pyrroles: Multi-component Reaction of Oxalyl Chloride

A novel, convenient and efficient approach to synthesis of pyrrole derivatives via the reaction of primary amines, alkyl propiolates and oxalyl chloride is described. The method offers several advantages including high yields of products and performing reaction in water as the solvent. 

A novel and highly efficient esterification process using triphenylphosphine oxide with oxalyl chloride

Triphenylphosphine oxide (TPPO) and oxalyl chloride ((COCl)2) are used as novel and high-efficiency coupling reagents for the esterification of alcohols with carboxylic acids via the TPPO/(COCl)2 system at room temperature for 1 h. The reaction represents the first TPPO-promoted esterification under mild and neutral conditions with excellent yields. Furthermore, we proposed a plausible mechanis...

thionyl chloride (or oxalyl chloride) as an efficient acid activator for one-pot synthesis of β-lactams

thionyl chloride (or oxalyl chloride) has been used as an efficient and cheap acid activator for one-pot synthesis of β-lactams in good to excellent yields by reaction between imines and acids in the presence of triethylamine at room temperature.
