C(1)-vinylation of [closo-1-CB9H10]– (A) and [closo-1-CB11H12]– (B) with 4-benzyloxystyryl iodide followed by hydrogenation of the double bond and reductive deprotection of the phenol functionality led to C(1)-(4-hydroxyphenethyl) derivatives The phenol functionality was protected as the acetate. The esters were then treated with PhI(OAc)2 and the resulting isomers were separated kinetically (for derivatives of anion A) or by chromatog. (for derivatives of anion B) giving the difunctionalized building blocks in overall yields of 9% and 50%, resp. A similar series of reactions was performed starting with anions A and B and 4-methoxystyryl bromide and iodide. Significant differences in the reactivity of derivatives of the two carborane anions were rationalized with DFT computational results. Application of the difunctionalized carboranes as building blocks was demonstrated through preparation of two ionic liquid crystals. The extensive synthetic work is accompanied by single crystal XRD anal. of six derivatives This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0Quality Control of Tetramethylammonium chloride).
Tetramethylammonium chloride (cas: 75-57-0) belongs to organic chlorides. Organic chlorides can be used in production of: PVC, pesticides, chloromethane, teflon, insulators. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Quality Control of Tetramethylammonium chloride
