Deprotection of acetals and ketals can be achieved by using sodium tetrakis(3,5-trifluoromethylphenyl)borate (NaBArF 4) as the catalyst in water at 30 °C. For example, a quantitative conversion of 2-phenyl-1,3-dioxolane into benzaldehyde was accomplished within five minutes by using this sodium salt (0.1 mol%) in water.
使用四(3,5-三氟甲基苯基)硼酸钠(NaBArF 4)作为催化剂,在30°C的水中可以实现缩酮和缩醛的去保护。例如,通过在水中使用这种钠盐(0.1摩尔%),2-苯基-1,3-二氧戊环在五分钟内实现了定量的转化为苯甲醛。
