- W2019950705 abstract "Treatment of Fe(NO) 2 [PR 3 ](CO) with tetracyanoethylene (TCNE) in diethyl ether leads to the formation of Fe(NO) 2 [PR 3 ]( η 2 -TCNE), where PR 3 =P(OCH 3 ) 3 , 1 , P( n -Bu) 3 , 2 , PMe 2 Ph, 3 , and PEt 2 Ph, 4 . An X-ray crystallographic study of 1 shows the iron to be situated in a nearly tetrahedral environment with a π -bonded tetracyanoethylene and two linearly bound nitrosyl groups. From the ambient-temperature NMR spectral data, it is evident that there exist two non-equivalent cyanocarbon environments, indicating that the rotation about the Fe-TCNE π -bond is slowed at room temperature; variable-temperature NMR studies on Fe(NO) 2 [P(OMe) 3 ]( η 2 -TCNE), 1 , yielded an activation energy barrier of approximately 18.1±0.5 kcal mol −1 for this rotational process. Electrochemical studies revealed that the neutral Fe(NO) 2 [PR 3 ]( η 2 -TCNE) complexes undergo irreversible reductions at positively shifted potentials, relative to the related Fe(NO) 2 [PR 3 ](CO) complexes. Moreover, a trend toward cathodic shift of the reduction potentials with increasing phosphine p K a has been observed. The high energy barrier for alkene rotation and the shift towards positive reduction potentials are rationalized in terms of a strong π -interaction between the iron center and TCNE." @default.
