“…This reagent can be prepared easily by the method of Rowe, Furnas, and Bliss. 983 The evaluation of unsaturation in mixtures of hydrocarbons by means of pyridine sulfate dibromide was introduced by Wilson. If it is used as a brominating agent, the danger of forming bromine substitution compounds is eliminated and better results are obtained.…”

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.

Industrial evaluation of allyl starch as a coating material in the late 1940's established that properties such as brittleness, nonhomogeneity of product, solvent solubility, and poor water resistance limited its potentialities to specialty uses. Infrared absorption analysis of allyl dextrin coatings before and after curing established that 50% of the allyl groups oxidatively polymerized. Since some degradation occurs in this process, attempts were made to limit this degradation and to improve coating properties by polymerizing pendant allyl groups with free‐radical initiators. Homopolymerization studies involving effets of molecular size and dextrin concentration indicated that intra‐molecular polymerization dominated early stages of the reaction. Graft copolymerization of a few unsaturated monomers resulted in products containing 3.6% acrylonitrile, 8.5% acrylic acid, and 15–18% acrylamide. Only with the acrylamide did no concurrent homopolymerization of dextrin allyl groups occur. Neither variations in method for polymerizing the allyl dextrins nor use of copolymers was effective in producing suitably cured coatings.
