A general approach to substituted diphenyldiazenes

摘要: Abstract A general and practical synthetic method for the construction of unsymmetrically substituted diphenyldiazenes based on classical azo coupling reaction has been developed. key feature this is use N,N-diallyl protected aniline derivatives as components. The moiety component warrants sufficient reactivity allows to avoid formation constitutional isomers resulting from intermediate triazene formation. Furthermore, subsequent reaction, aminofunction, can be replaced by other substituents including hydrogen via diazonium ion intermediates. In general, following approach target compounds obtained in reasonable good yields.
