From the cycloaddition of acetonitrile N-oxide with indene two isomeric methyldihydroindenoisoxazoles have been isolated. Elucidation of their structures by bromination and 1H n.m.r. spectroscopy, and related reactions on analogous compounds are described.
从乙腈N-氧化物与茚的环加成中,已经分离出两种异构体甲基二氢茚并异恶唑。描述了通过溴化和1 H nmr光谱对其结构的阐明,以及对类似化合物的相关反应。

In contrast to reactions of the bis(pentamethylcyclopentadienyl)titanium system, substituted allyl complexes of the electron-rich bis(2-piperidinoindenyl)titanium(III) template are converted to 2,3-disubstituted titanacyclobutane complexes by free radical alkylation at the allyl central carbon.
