3-methyl isomers, as unequivocally established by XRD analysis of a representative product. A correction is therefore provided here in order to rectify the previous erroneous assignment of the position of the methyl group. Moreover, the process has been generalized to substrates bearing an internal triple bond, which lead to 3-alkyl-2-methyl-1-thia-4a,9-diazafluoren-4-ones, whose structure was confirmed by
钯催化的带有末端三键的2-(丙炔硫基)苯并咪唑的羰基化反应导致生成2-甲基-1-硫代-4a,9-二氮杂芴-4-酮,而不是先前报道的3-甲基异构体。代表性产品的XRD分析。因此,在此提供一种校正,以校正先前对甲基位置的错误分配。此外,该方法已推广到带有内部三键的底物上,该底物产生了3-烷基-2-甲基-1-硫杂-4a,9-二氮杂芴-4-酮,其结构已通过XRD分析了两种代表性衍生品。
