Diazonium compound information

Diazonium compounds or diazonium salts are a group of organic compounds sharing a common functional group [R−N+≡N]X− where R can be any organic group...

coupling is an reaction between a diazonium compound (R−N≡N+) and another aromatic compound that produces an azo compound (R−N=N−R’). In this electrophilic...

diazo compound is diazomethane, CH2N2. Diazo compounds (R2C=N2) should not be confused with azo compounds (R−N=N−R) or with diazonium compounds (R−N+2)...

reaction is a chemical reaction used to synthesize aryl halides from aryl diazonium salts using copper salts as reagents or catalysts. It is an example of...
