The triazene moiety as a protecting group for aromatic amines
摘要:
Reaction of (2-,(3-, and (4-bromophenyl)-3,3-(1,4-butanediyl)triazenes (derived from the corresponding 2-, 3-, and 4-bromoanilines) with sec- or tert-butyllithiums gave the corresponding (triazenylaryl)-lithiums; these intermediates reacted with a variety of electrophiles to give substituted aryl triazenes. These products cound be converted to substituted anilines by reduction or to novel substituted aromatics by a modified Sandmeyer reaction.

Unprotected indoles are prepared with the title method, which has a wide scope for alkynes. Excellent regioselectivity was accomplished for aryl–alkyl and alkyl–alkyl disubstituted acetylenes. This reaction features an unusual 1,2 rhodium migration and ring‐contraction‐triggered NN bond cleavage. It allows rapid conversion of the reaction products into several functional molecules.

reaction conditions. Based on this optimum C–H/C–H couplingapproach, three new organic sensitizers are readily prepared and submitted to solarcell device fabrications, giving the power conversion efficiency (PCE) up to 4.85%. This work constitutes the first example that connects high atom-efficiency C–H/C–H green catalysis with dye-sensitizedsolarcell applications.
The palladium-catalyzedcross-couplingreaction of 1-aryltriazenes with aryl- and alkenyltrifluorosilanes occurs readily at room temperature to yield the corresponding biaryl and stilbene products in moderate to good yields. In contrast to the previous results for the reaction with areneboronic acids, in which an additional Lewis acid such as boron trifluoride is essential for the activation of the
