The nucleophilic cyclopropanation of hexa-1,5-diene-3,4-diones with bis(iodozincio)methane afforded the Zn alkoxides of cis-dialkenylcyclopropane-1,2-diols stereoselectively. The subsequent oxy-Cope rearrangement afforded the corresponding Zn alkoxides of

Treatment of 1,6-dialkylhexa-1,5-diene-3,4-diones with bis(iodozincio) methane at-78 °C for several hours gave cisdialkenylcyclopropane-1,2-diols which rearranged into the zinc alkoxides of cis-5,6-dialkylcyclohepta-3,7-diene- 1,3-diol in good yields at r

Treatment of 1,6-dialkylhexa-1,5-diene-3,4-diones with bis(iodozincio) methane gave zinc alkoxides of cis-5,6-dialkylcyclohepta-3,7-diene-1,3-diol in good yields at room temperature. The reaction proceeded with high stereospecificity. Bis(iodozincio)metha
Reactions of Fischer carbene complexes with siloxydienes: Formation of cycloheptadiene and cyclopentene derivatives - Formal [2+1] cycloaddition followed by cope rearrangement versus formal [3+2] cycloaddition with or without preceding carbene-ligand meta

Thermal reactions of the α,β-unsaturated Fischer carbene complexes 3-5 with the siloxydienes 6 and 7 mainly furnished the expected cyclohepta-1,4-dienes such as 9, 10, 12, 14, and 15, whose formation is explained by a formal [2+1] cycloaddition followed b
