REGIO- AND STEREOCONTROLLED FUNCTIONALIZATION OF CYCLOHEPTADIENE USING ORGANOIRON AND ORGANOSELENIUM CHEMISTRY.

Whereas the reactions of tricarbonylcycloheptadienyliron salts with nucleophiles generally occur in low yield giving mixtures of products, the corresponding dicarbonyl(triphenylphosphine) and dicarbonyl(triphenyl phosphite) complexes 8 give high yields of single adducts on reaction with a range of nucleophiles. The regioselectivity of nucleophile addition to 8 is strongly dependent on the nucleophile, 'soft' nucleophiles attacking C-1, 'hard' nucleophiles attacking C-2 of the dienyl ligand. The diene complexes 10 resulting from C-1 addition can be reactivated by hydride abstraction with Ph//3C** plus PF//6** minus , to give dienyl complexes 11, which undergo a second nucleophile addition regio- and stereospecifically (trans to the Fe(CO)//2L group). Decomplexation is easily accomplished, leading to cycloheptadienylacetic acid derivatives.
