  摘要：

  The lithiation of indole, using a slight excess of n-butyl lithium in THF, followed by methylation and reaction with [Cr(CO)(6)] in refluxing dibutyl ether, resulted in the formation of [Cr(eta (6)-N-methylindole)(CO)(3)] (1a) and [Cr(eta (6)-N-methyl-2-methyl-2-methylindole)(CO)(3)] (1b). In contrast, lithiation of quinoline in THF, silylation and the subsequent reaction with [Cr(CO)(6)] under similar reaction conditions, afforded [Cr(eta (6)-N-trimethylsilyl-2-butyl-1,2-dihydroquinoline)(CO)(3)] (2) and [Cr(eta (6)-{2-butyl 1,2,3,4-tetrahydroquinoline})(CO)(3)] (3). The formation of [Cr(eta (6)-2,2'-bis{N-methylindolyl})(CO)(3)] (4) implied lithiation at the 2-position of 1a. However, metallation at the 7-position was also indicated during the same reaction. In the presence of [Mn(CO)(5)Br], product 4 and the transmetallation product [Cr(eta (6)-{7-(N-methylindolyl)Mn(CO)(5)})(CO)(3)] (5) were isolated. Reaction with titanocene dichloride gave [Cr(eta (6)-{2-(N-methylindolyl)TiCp2Cl})(CO)(3)] (6), which slowly converted into [TiCp2{Cr(eta (6)-2-(N-methylindolyl) (CO)(3)}(2)] (7).
