发明名称 Preparation of Brominated Indanes
摘要 <p>Ar-brominated indanes having a purity of 92% by weight or more are produced without recrystallization by an improved process. The process comprises the steps of: (a) adding an indane compound to an organic solvent solution of bromine in the presence of an ar-bromination catalyst at a rate such that said addition is completed within 1.5 hours, with the proportions of indane compound and solvent being selected such that the weight ratio of solvent to indane compound in the reaction is less than 20 grams of solvent per gram of indane compound, and then (b) heating the reaction mixture to a temperature of at least 75 DEG C so as to produce said poly-ar-brominated indane product.</p>
