“…Hossein et al reported the synthesis and applications of the polymeric tribromide reagent poly(diallyldimethylammonium tribromide) (PDADMATB). 1203 For the preparation of this compound, poly(diallyldimethylammonium bromide) was treated with KBr, followed by oxidation of bromide to bromine with an aqueous solution of oxone (Scheme 425). This supported tribromide was used in α-bromoacetalization of ketones, bromination of alkenes, and regioselective bromination of activated aromatic compounds (Scheme 426).…”

Bromination is one of the most important transformations in organic synthesis and can be carried out using bromine and many other bromo compounds. Use of molecular bromine in organic synthesis is well-known. However, due to the hazardous nature of bromine, enormous growth has been witnessed in the past several decades for the development of solid bromine carriers. This review outlines the use of bromine and different bromo-organic compounds in organic synthesis. The applications of bromine, a total of 107 bromo-organic compounds, 11 other brominating agents, and a few natural bromine sources were incorporated. The scope of these reagents for various organic transformations such as bromination, cohalogenation, oxidation, cyclization, ring-opening reactions, substitution, rearrangement, hydrolysis, catalysis, etc. has been described briefly to highlight important aspects of the bromo-organic compounds in organic synthesis.

“…The weakening of the C2 and C3 peaks is because after coating the surface of the paper mulch with AKD, the cellulose on the surface of the paper mulch is covered. Meanwhile, there is a Cl2p peak on the surface of the AKD-coated paper mulch, and the Cl element mainly comes from AKD [65]. All XPS data here have also been corrected for C1s spectra.…”

Livestock dung, discarded crop straws, and residual plastic film are the primary agricultural non-point sources of pollution. For livestock dung and discarded crop straw, the general treatment focuses on compost, animal fodder, industrial raw material, and new energy. The development of degradable mulch film is the main way to solve pollution from residual plastic film. However, an effective way to solve the above three types of pollution simultaneously and use them for ecological circular agriculture has been less studied. In this study, using cow dung and flax straw wastes as raw materials, we prepared natural, fibre-based paper mulch using the rapid-Kothen method and analysed the film-forming mechanism. Based on the Van Soest method, the cow dung and flax straw waste contain abundant cellulose fibres: 36.75% and 54.69%, respectively. The tensile strength and tear strength of fibre paper mulch are 1.87 kN/m and 19.91 N/mm, respectively. To enhance the adaptability of the fibre paper mulch in humid environments, the surface of the mulch was treated with alkyl ketene dimer (AKD). The AKD-coated fibre paper mulch displays hydrophobic properties, indicated by a contact angle of 128° ± 2°. It has a wet tensile strength of 0.64 kN/m and a wet tear strength of 8.23 N/mm. Additionally, it exhibits a dry tensile strength and a tear strength of 2.13 kN/m and 16.43 N/mm, respectively. Notably, the dry tensile strength is increased by 16.31%. In this way, the livestock dung and discarded crop straw can be reused, reducing dung pollution and straw burning in livestock farms, and the final products can alleviate the residual film pollution simultaneously.

“…α-Haloketone acetals are generally prepared via two step strategy involving the α-halogenation of ketones [5] followed by the acetalization of the resulting α-haloketone [6]. Alternatively, one step direct haloacetalization of ketones to α-haloketone acetals has been accomplished using halogenating agents such as Nhalosuccinimide [7], 1,3-dihalo-5,5-dimehtylhydantoin [8], bromine [9], iodobenzene dichloride [10], copper(II)bromide [11], and poly(diallyldimethylammonium chloride) [12].…”

Synthesis of 2,3-diaryl acrylic acid is accomplished using the Perkin reaction between aromatic aldehyde and variously substituted phenyl acetic acids in presence of acetic anhydride and triethylamine at reflux condition. The reaction of resulting 2,3-diaryl acrylic acids with (diacetoxyiodo)benzene and tetraethylammonium bromide in MeOH/H2O forms 2-bromo-1,2-dimethoxy-1,2-diarylethane in moderate to good yields. The structure of the synthesized products was characterized by FTIR, 1H, 13C NMR spectroscopy and mass spectrometry. This is an unusual reaction observed for α,β-unsaturated carboxylic acids under transition metal-free oxidative condition.
