The scope of a set of recently reported hydrazine reagents has been explored with respect to arylation. Compounds of type R1NHNHCOR2 can be selectively arylated under very mild conditions using triarylbismuth diacetates.
Zinc-Mediated Allylation and Benzylation of Phenylazocarboxylic Esters
Lasch, Roman,Heinrich, Markus R.
, p. 10412 - 10420 (2015)
Allylation and benzylation of phenylazocarboxylic tert-butyl esters have been achieved under Barbier-type reaction conditions and in very short reactions times using the corresponding allyl and benzyl bromides or iodides in combination with zinc powder. Whereas all reactions occurred exclusively at the β-nitrogen atom of the azocarboxylic esters, the linkage of allyl units was shown to depend on the substitution pattern at the double bond of the allyl halide. The hydrazines obtained are useful precursors for indoles and indazoles.
