CAS 24424-99-5 Di-tert-butyl dicarbonate | Products & Prices & Suppliersts
White to off-white microcrystalline powder Di-tert-butyl dicarbonate (Boc2O) and di-tert-butyl tricarbonate ((BocO)2CO)? have been used as amine carbonylating reagents to obtain linear or branched aliphatic isocyanates.most of the known methods for transforming amines into isocyanates are not mild enough and furnish undefined products as a result of uncontrolled side reactions. However, 4-dimethylaminopyridine (DMAP)-catalyzed reaction with activated carbonates as C1 building blocks cons
