Variable temperature 13C and 31P NMR spectroscopy has been used to establish solution structures and conformer populations for a variety of cyclic and acyclic (diene)Fe(CO)2L complexes (L = phosphine, phosphite, isonitrile).The solid state structures of (2,3-dimethylbutadiene)Fe(CO)2PPh3 and (trans,trans-2,4-hexadiene)Fe(CO)2PPh3 have been determined and used as a basis for molecular modelling of steric effects in these complexes.
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.
NATURAL PRODUCTS SYNTHESIS USING ORGANOIRON COMPLEXES.
Pearson
, p. 1767 - 1779 (2008/10/08)
A survey is presented of applications of dienyl-Fe(CO)//2L complexes as intermediates for natural products synthesis, based on (a) complexes which act as cyclohexenone gamma -cation equivalents, and (b) the ability of the metal to direct the stereochemistry of C-C bond formation in seven membered rings.
