実験手順
Similarly, 1,2-butanediol and 2,3-butanediol were heated with equivalent quantities of hexachloroacetone in the presence of K2CO3 or other such basic catalyst as previously defined to produce comparable yields of 1,2-butylene carbonate and 2,3-butylene carbonate, respectively. Also, 3-chloro-1,2-propanediol was reacted in this way with hexachloroacetone to make 4-(chloromethyl)-1,3-dioxol-2-one (chloromethylethylene carbonate). In the same way, styrene glycol (1-phenyl-1,2-ethanediol) is reacted with hexachloroacetone in the presence of a basic catalyst to produce 1-phenylethylene carbonate (4-phenyl-1,3-dioxol-2-one), 1,2-hexanediol is reacted with hexachloroacetone to produce 1,2-hexylene carbonate (4-butyl-1,3-dioxol-2-one), and 1-cyclohexyl-1,2-ethanediol is reacted with hexachloroacetone to make 4-cyclohexyl-1,3-dioxol-2-one (cyclohexylethylene carbonate).
