Synthesis and Crystal Structure Determination of [H2‐cryptand 222](Br3)2: A Unique Tribromide Catalyst for the Catalytic Chemoselective N‐Boc Protection of Amines
Journal of the Chinese Chemical Society Vol. 58, No. 4, 538–543
Abstract The organic tribromide, [H2‐cryptand 222](Br3)2 was synthesized and characterized by X‐ray crystallography, and was utilized as an active catalyst for the N‐boc protection of amines. The method is general for the preparation of N‐b…
