Treatment of di-Me tricyclo[4.2.2.02'5]deca-3,7,9-triene-7,8-dicarboxylate (1) with nonacarbonyldiiron led to di-Me 7-10-tetrahaptotricyclo[4.2.2.02,5]deca-3,7,9-triene-7,8-dicarboxylate tricarbonyliron (I). This deriv. reacted smoothly with several 1,3-dipoles (nitrones, nitrile oxides, nitrile imines and diazoalkanes) at the cyclobutene double bond to give adducts from which the tricarbonyliron group could be easily removed by oxidative decomplexation with trimethylamine N-oxide.

Abstract

This deriv. reacted smoothly with several 1,3-dipoles (nitrones, nitrile oxides, nitrile imines and diazoalkanes) at the cyclobutene double bond to give adducts from which the tricarbonyliron group could be easily removed by oxidative decomplexation with trimethylamine N-oxide.File in questo prodotto:
