tert-Butyl carbamate Usage And Synthesis

Chemical Properties	White to slightly yellow needles
Uses	tert-Butyl carbamate was used in palladium-catalyzed synthesis of N-Boc-protected anilines. It was used in the synthesis of tetrasubstituted pyrroles, functionalized with ester or ketone groups at C-3 position.
Synthesis Reference(s)	The Journal of Organic Chemistry, 28, p. 3421, 1963 DOI: 10.1021/jo01047a033
General Description	Palladium-catalyzed cross-coupling reaction of tert-butyl carbamate with various aryl(Het) halides with Cs₂CO₃ as base in 1,4-dioxane (solvent) has been investigated.
