卤代甲基硼酸盐衍生物与锂酯烯醇酸盐形成“酸盐”配合物，在室温下相对稳定，可以通过B-11核磁共振观察到，卤代甲基硼酸盐衍生物与酯、酮或酰胺烯醇酸盐反应可得到相应的β -硼酸羰基衍生物，收率为43-83%。
Halomethylboronate derivatives form ''ate''-complexes with lithium ester enolates, which are relatively stable at room temperature and can be observed by B-11 N.M.R. Reaction of an iodomethylboronate derivative with either an ester, ketone or amide enolate provides the corresponding beta-boronate carbonyl derivatives in 43-83% yield.
