Imidazole and Triazole Coordination Chemistry for Antifouling Coatings

Scheme 9

Dipolar 1,3-cycloaddition of an azide and an alkyne. The regular Huisgen 1,3 dipolar cycloaddition between an azide and an alkyne results in a mixture of 1,4- and 1,5 substituted triazoles [117]. The CuAAC reaction is stereospecific and yields 1,4 substituted triazoles [118]. The reaction can also be catalysed by Ru(II) which yields 1,5 substituted triazoles [119].
