16526778-1	2006	2,3-Disubstituted benzo[b]selenophenes have been prepared by the electrophilic cyclization of various 1-(1-alkynyl)-2-(methylseleno)arenes by Br2, NBS, I2, ICl, PhSeCl, PhSeBr, and Hg(OAc)2.	Bromine	142-145	nibrin	Homo sapiens	147-150	
30836604-2	2019	The reaction proceeds via in situ formation of alpha-bromoketone using NBS as a bromine source as well as an oxidant, followed by trapping with suitable nucleophiles to provide the corresponding products in good yields under metal-free conditions.	Bromine	80-87	nibrin	Homo sapiens	71-74	
23368840-1	2013	A one-pot cascade transformation of chalcones into beta-imidoketones has been developed, in which NBS provides both electrophilic bromine and nucleophilic nitrogen sources, and DBU functions as a nucleophilic reagent to activate NBS to be a more electrophilic bromine species and to further remove the bromine of alpha-bromoketones.	Bromine	130-137	nibrin	Homo sapiens	98-101	
18219426-0	2008	Aminobromination of olefins with TsNH(2) and NBS as the nitrogen and bromine sources mediated by hypervalent iodine in a ball mill.	Bromine	69-76	nibrin	Homo sapiens	45-48	
16626117-1	2006	Highly substituted 1H-isochromenes, isobenzofurans, and pyranopyridines can be prepared by allowing o-(1-alkynyl)arenecarboxaldehydes and ketones to react with I2, ICl, NIS, Br2, NBS, p-O2NC6H4SCl, or PhSeBr and various alcohols or carbon-based nucleophiles at room temperature.	Bromine	174-177	nibrin	Homo sapiens	179-182	
24102289-2	2013	Dual activation of NBS or NBP by DBU leads to more electrophilic bromine and more nucleophilic nitrogen atoms simultaneously.	Bromine	65-72	nibrin	Homo sapiens	19-22	
19108612-1	2009	The regio- and stereoselective aminobromination of alpha,beta-unsaturated ketones catalyzed by copper powder has been established with 4-TsNH(2) and NBS as the nitrogen/bromine sources, respectively.	Bromine	169-176	nibrin	Homo sapiens	149-152	
12956066-5	2003	The choice of NBS or chlorine for allyl halide synthesis is shown to depend on the potential to avoid competing reactions, such as halolactonization of leucine derivatives with chlorine, and hydrogen abstraction and bromine incorporation at multiple sites on treatment of isoleucine derivatives with NBS.	Bromine	216-223	nibrin	Homo sapiens	14-17	
10814190-4	2000	The different reactivities of NBS and NCS are ascribed to the relative amounts of free halogen produced (due to differences in N-X bond strengths involving Br and Cl), and the different sizes of the halogens.	Bromine	156-158	nibrin	Homo sapiens	30-33	
10814190-10	2000	This effect is probably due to an increase in the amount of bromine produced from NBS in the presence of iodine.	Bromine	60-67	nibrin	Homo sapiens	82-85	
12633091-0	2003	Transition metal-catalyzed regio- and stereoselective aminobromination of olefins with TsNH2 and NBS as nitrogen and bromine sources.	Bromine	117-124	nibrin	Homo sapiens	97-100
