1,6- and 1,7-dienes and -enynes incorporating a silicon-oxygen or silicon-nitrogen link are co-cyclised with zirconocene(1-butene) or diisopropoxytitanium(propene) to give metallabicycles. Further elaboration followed by cleavage of the silicon-carbon bond using Tamao oxidation affords a wide variety of organic products.
含有硅氧键或硅氮键的 1,6- 和 1,7- 二烯和烯炔与锆碳(1-丁烯)或二异丙氧基钛(丙烯)共循环,生成金属双环。进一步加工后,使用 Tamao 氧化法裂解硅碳键,可得到多种有机产品。
