Examination of Synthetic Routes to Monosubstituted Diimides. II. Synthesis of t-Butyl Aryl- and Acylazoformates. Acid-Induced Cleavage of the Thionocarbo-t-butoxy Group^1,2

Investigation of the oxidation ability of protected hydrazine derivatives

“…After 20 min the solution was filtered and CH 2 Cl 2 evaporated, furnishing 581 mg (92%) of PhN=NBoc as an orange liquid, pure by TLC and NMR after lit. 7 1 H NMR (CDCl 3 ): 1.66 (s, 9H, Boc), 7.5-7.6 (m, 2H, C 6 H 5 ), 7.8-7.9 (d, 3H, C 6 H 5 ). 13 …”

Azo Compounds

“…Some workers carry the reaction out at room temperature [85,86,96], others at ice or lower temperatures [97]. Reaction conditions are somewhat variable.…”

Di-tert-butyl Azodicarboxylate

“…It is a light-sensitive compound with a melting point in the range of 90-92 °C. 1 DBAD (1) has been widely used for several important reactions and for the synthesis of natural and biological active compounds. Recently, several examples have been published showing the relevance of this reagent in key organic reactions, especially in the α-amination of carbonylic compounds.…”
