Regioselective Addition of Various Heteronucleophiles to (Styrene)Cr(CO)3 Complexes
摘要:
(Styrene)Cr(CO)(3) complexes underwent the addition of various heteronucleophiles such as alcohols, amines, and thiols, in the presence of KOH, and the beta-addition products were selectively obtained in moderate to excellent yields. The structural details and features of the product complexes were also elucidated.
The reaction of the BH3-THF reagent with benchrotrenic alkenes, followed by a water addition and the formation of hydrogenated products are described. This formation and the regioselectivity observed is a consequence of the electron withdrawing effect of the Cr(CO)3 group.
