Intramolecular reductivecoupling of nitrite with alkene units in the presence of zirconocene prepared from (C5H5)2ZrCl2 and BuLi gives cyclic ketones; the intermediary metallacycle prepared from the 2-cyano-N-allylaniline derivative is very reactive and provides various quinoline derivatives by treatment with electrophiles and other reagents.
在由(C 5 H 5)2 ZrCl 2和BuLi制得的茂茂锆存在下,亚硝酸盐与烯烃单元的分子内还原偶联反应得到环状酮。由2-氰基-N-烯丙基苯胺衍生物制备的中间体金属环烷具有很高的反应活性,并通过亲电试剂和其他试剂处理可提供各种喹啉衍生物。

TMS ethers of 1-alkenyl-1-cycloalkanols readily rearranged to the ring expanded β-mercurio cycloalkanones via mercurinium ions, which could be converted into α-methylene cycloalkanones through elimination and further one carbon expanded cycloalkanones via free radical chain reactions.
