Diethyl 1-phenyl-1-trimethylsiloxymethane phosphonate carbanion was found to react as an effective acyl anion equivalent in the preparation of α-hydroxy ketones from aliphatic and aromatic aldehydes and ketones. A 1,4-oxygen-oxygen silicon migration was also observed.
在由脂族和芳族醛和酮制备α-羟基酮中,发现二乙基1-苯基-1-三甲基甲硅烷氧基甲烷膦酸酯碳负离子作为有效的酰基阴离子当量反应。还观察到1,4-氧-氧硅迁移。
