The anion of the title compound, simply generated in the presence of catalytic amount of triethylamine, acts as nucleophilic acylating equivalent of formaldehyde reacting with both common electrophilic olefins or aldehydes to give moderate to good yield of Michael or aldol adducts respectively, which are easily hydrolized by dilute acid at ambient to temperature to afford the corresponding aldehydes
标题化合物的阴离子是在催化量的三乙胺存在下简单产生的,它充当甲醛的亲核酰化当量,与常见的亲电子烯烃或醛反应,分别产生中等至良好收率的Michael或Aldol加合物,易于水解在室温至室温下用稀酸稀释,得到相应的醛。
