The title compound was prepared by the treatment of the corresponding 1,1-dibromocyclopropane with lithium naphthalene radical anion (Li-C10H8). Trapping of the dilithio compound by chlorotrimethylsilane provided evidence for its highly basic profile which can compete with silylation.
标题化合物是用萘基阴离子锂(Li-C10H8)处理相应的 1,1-二溴环丙烷而制备的。用三甲基氯硅烷捕获二硫代化合物证明了它的高碱性特征,这可能会与硅烷化作用产生竞争。
