摘要:
[(Benzothiophene)Mn(CO)(3)]X (X(-)=BF4- (1), ClO4- (2)) has been synthesized by treatment of benzothiophene with Mn(CO)(5)X in methylene chloride. Reaction of 1 with nucleophiles has been studied, When NaBH3CN, EtMgBr and NaP(O) (OMe)(2) were reacted with 1, C7 and C4 additions were obtained in the ratio of 1:1-3:1. When PhMgBr, MeLi, LiCH2CN and LiCH(2)CO(2)(t)Bu were added to 1, C7 and C4 adducts were obtained as major products in the ratio of 1:1-2:1 and C5 and C6 adducts were obtained as minor products. The molecular structures of the hydride adduct 3A (monoclinic; space group P2(1)/n; cell parameters a=7.203(4), b=12.953(4), c=12.301(3) Angstrom, beta=106.03(2)degrees; Z=4; R=6.31, wR(2)=16.48%) and the phenyl adduct 5A (monoclinic; space group P2(1)/n; cell parameters a=7.925(7),b=16.390(3), c=11.865(2) Angstrom, beta=92.81(3); Z=4; R=5.36%, wR(2)=14.19%) have been determined.
