Hydroboration of the syn, anti-[Fe (CO)3]2 double complex 24 of the readily available 5,6,7,8-tetramethylidene-2-bicyclo [2.2.2]octene (22) gave the corresponding doubly complexed 2-bicyclo [2.2.2]octanol 25. Cr03-oxidation furnished ketone 27. The syn-Fe (CO)3-groups in 25 and 27 were oxidized sele
Pd-catalyzed double carbomethoxylation of the Diels-A lder adduct of cyclopentadiene and maleic anhydride yielded the methyl norbornane-2,3-endo-5,6-exotetracarboxylate (4) which was transformed in three steps into 2,3,5,6-tetramethyIidenenorbornane (1). The cycloaddition of tetracyanoethylene (TCNE
