[reaction: see text] A new electrophilicamination reaction of functionalized arylazo tosylates with alkylzinc halides or dialkylzinc reagents in THF leads to the corresponding hydrazines. A facile cleavage of the N-N bond is achieved using Raney nickel in refluxing ethanol, leading to substituted secondary aryl-alkylamines in 45-79% yield.
