Synthesis of Quaternary Salts from 3,3′ -Bipyridine and Dibromoalkanes
2014
Singh, Shyam K. | Summers, Lindsay A. | Hick, Larry A.
Reaction of 3,3'-bipyridine with 1,3-dibromopropane, 1,4-dibromobutane, 1.5-dibromo-pentane, 1,6-dibromohexane. 1,7-dibromoheptane and 1.8-dibromooctane affords the corresponding bridged diquaternary salts, the structures of which were confirmed by fast atom bombardment mass spectrometry. Reaction with 1,2-bromoethane gives instead 1.1"-(1,2-ethanediyl)-bis-3.3'-bipyridinium dibromide.
