3,5-Dichlorophenyldiazonium tetrafluoroborate CAS:350-67-4

3,5-Dichlorophenyldiazonium tetrafluoroborate is a chemical compound that is commonly used in organic synthesis. It is a diazonium salt, which means it contains a diazonium group (N2+) attached to a phenyl ring that is substituted with chlorine atoms at the 3rd and 5th positions.

This compound is often employed in reactions that involve coupling with other aromatic compounds. It can undergo reactions such as electrophilic aromatic substitution, where it can transfer its diazonium group to another nucleophilic aromatic compound to form a new bond. This is particularly useful for the introduction of functional groups onto aromatic rings.
