Hydrothermal synthesis of a ZSM-5/MCM-41 composite has been carried out from pre-synthesized ZSM-5 zeolite as a silica source and CTAB as a template. The ZSM-5/MCM-41 composite materials were further loaded with varying wt% of cobalt with respect to

An expeditious catalyst-free cascade coupling of N,N-dibromoarylsulfonamides with isonitriles and amines via carbodiimide intermediates has been developed. The protocol represents an elegant pathway for sulfonyl guanidines at room temperature within

An unprecedented 1,3-migration of the tert-butyl group was observed while reacting tert-butyl isonitrile with N,N-dibromoaryl sulfonamides and nitrile. The reaction involves the simultaneous C–N single bond scission of isonitrile and the migration

A rapid process for decarboxylative bromination of α,β-unsaturated carboxylic acids have been developed using N,N-dibromo-p-toluenesulfonamide (TsNBr2). Treatment of cinnamic acids with TsNBr2 in presence of potassium carbonate in acetonitrile prod

A metal free protocol for the synthesis of quinoxalines from alkynes has been developed. The reaction was carried out by treating alkynes with TsNBr2 in presence of O-phenylenediamines in a mixture of acetonitrile and water (9:1). This one-pot reacti

A new approach has been developed for oxidative transformation of alkynes by controlled manipulation of TsNBr2 mediated process. Alkynes could be readily converted to ketones and α-bromoketones via an oxybromination–debromination sequence. When al

TsNBr 2 reacts readily with olefins to produce α-bromo ketones at room temperature. The synthesis was carried out by treating an olefin with TsNBr 2 in acetone–water mixture in 30:1 ratio. Excellent yield of corresponding α-bromo ketone could be
