Cycloadditions of Organometal Fragment-Substituted Alkenes, I. - [3 + 2] Cycloaddition of η1-Allyl Iron Complexes with Nitrile Oxides: Ferriomethyl-Substituted IsoxazolinesThe isoxazolines C5H5(OC)(L)Fe-CH2-CH-CH2-C(R) = N-O (3a-f) [R = Ph, 2,4,6-Me3C6H2; L = CO, P(OCH2)3CCH3, PPh3], substituted with a ferriomethyl group in 5-position, are obtained by 1,3-dipolar cycloaddition of the η1-allyliron complexes C5H5(OC)(L)Fe-CH2-CH=CH2 [L = CO (1a), P(OCH2)3CCH3 (1b), PPh3 (1c)] with the nitrile oxides RCNO [R = Ph (2a), Mst (2b)]. The chiral complexes 1b, c produce the diastereomeric isoxazolines 3b, c, e, f with diastereomer ratios of 59:41 to 93:7. The structure of 3d is established by crystal structure analysis.
