α-Methoxyvinyl complexes (Z)-(η5-C5H5)Re-(NO)(PPh3)(C(OCH3)=CHR) are readily alkylated (C6H5CH2Br, CH3I) to give acyl complexes (η5-C5H5)Re-(NO)(PPh3)(COCHRR') with high diastereoselectivity; the stereochemistry of these reactions, and probable transition-state geometries, are established by an X-ray crystal structure of the product (SR, RS)-(η5-C5H5)Re(NO)-(PPh3)(COCH(CH3)CH2C6H5). © 1985, American Chemical Society.
