TL;DR: The use of bromine and different bromo-organic compounds in organic synthesis is outlined and the scope of these reagents for various organic transformations such as bromination, cohalogenation, oxidation, cyclization, ring-opening reactions, substitution, rearrangement, hydrolysis, catalysis, etc is described briefly.

TL;DR: The use of molecular bromine in organic synthesis is well-known as discussed by the authors, however, due to the hazardous nature of bromines, enormous growth has been witnessed in the past several decades for the development of solid bromina carriers.

TL;DR: A catalyst-free protocol has been developed for amidation of alkyl aromatics and aldehydes using TsNBr(2)via a nitrene transfer process in the presence of a base in excellent yield within a short time.

TL;DR: Cuprous iodide has been found to be a very effective catalyst for allylation of aldehydes with allyltributylstannane as mentioned in this paper, and the catalytic system efficiently promotes the allylated reaction in DMF to produce homoallylic alcohols in high yield.

TL;DR: An expeditious catalyst-free cascade coupling of N,N-dibromoarylsulfonamides with isonitriles and amines via carbodiimide intermediates through an elegant pathway for sulfonyl guanidines at room temperature within a short time with high yields and wide substrate scope is developed.
