摘要：

KHCr(CO)(5) reacts with methyl acrylate in acetonitrile to give methyl propionate after acid hydrolysis. Monitoring the reaction by IR and NMR spectroscopy showed that the reaction mainly proceeds through the 1,2-addition product K+ [CH3CH(COOMe)Cr(CO)(5)](-). However, in situ formation of methyl propionate ca. 15%) before hydrolysis suggests that part of the reaction also occurs through the 1,4-adduct K+ [CH3CH=C(OMe)OCr(CO)(5)](-). The PPN+ salt of the 1,2-adduct obtained from ethyl acrylate was characterized by single crystal X-ray diffraction, (C) 2002 Published by Elsevier Science B.V.
