Abstract
The isoxazolines C5H5(OC)(L)Fe-CH2-H-CH2-C(R)= N-O (3a-f) [R = Ph, 2,4 ,6-Me3C6H2; L = Co, P(OCH2)3CCH3, PPh3], substituted with a ferriometh yl group in 5-position, are obtained by 1,3-dipolar cycloaddition of t he eta1-allyliron complexes C5H5(OC)(L)Fe-CH2-CH=CH2 [L = CO (1a), P(O CH2)3CCH3 (1b), PPh3 (1c)] with the nitrile oxides RCNO [R = Ph (2a), Mst (2b)], The chiral complexes lb, c produce the diastereomeric isoxa zolines 3b, c, e, f with diastereomer ratios of 59:41 to 93:7. The str ucture of 3d is established by crystal structure analysis.
