Alkene‐ and Alkyne‐substituted Methylimidazolium Bromides: Structural Effects and Physical Properties

Abstract

Abstract Several bromide salts composed of methylimidazolium cations possessing unsaturated sidechains (allyl‐, 3‐butenyl‐, propargyl‐, 2‐butynyl‐, and 2‐pentynyl‐) have been synthesized and characterized by multinuclear NMR, vibrational spectroscopy, DSC, and elemental analysis. Crystal structures of 1‐(2‐butynyl)‐3‐methylimidazolium bromide, 1‐propargyl‐3‐methylimidazolium bromide and 1‐allyl‐3‐methylimidazolium bromide, were determined.
