Benzo with oxalyl chloride

The isomeric benzo[l,2-A4,3- ]dithiophene-4,5-quinone is prepared in reasonable yields by a one-step Friedel-Crafts reaction of 3,3 -bithienyl with oxalyl chloride in refluxing 1,2-dichloroethane over 7-10 days (Equation 85) <2001JA11899>. [Pg.1172]

A variety of methods have been described to solve the task in solution.16 Common oxidative agents for this transformation include various heavy-metal reagents such as chromium-or ruthenium-based oxides, pyri-dine-S03, and dimethylsulfoxide (DMSO) in combination with acetic anhydride, carbodiimide, or oxalyl chloride for activation. One of the most prominent methods for the reliable conversion of sensitive compounds is the Dess-Martin reagent or its nonacetylated equivalent, 1-hydroxy-(17/)-benzo-l,2-iodoxol-3-one-l-oxide (2-iodoxybenzoic acid, IBX). [Pg.371]
