Alkylation of substituted 5,6-dihydro-1,2,4-triazolo[3,4- a ]isoquinolines with iodomethane, 2-iodopropane, or substituted benzyl halides (R—Hal) afforded quaternary 2-R-5,6-dihydro-1,2,4-triazolo[3,4- a ]isoquinolinium salts, for which a possibility of the formation of carbene PEPPSI complexes with palladium(ɪɪ) and pyridine, as well as 2-, 3-, and 4-picolines, was demonstrated.
碘甲烷、2-碘丙烷或取代苄基卤代物(R-Hal)对取代的5,6-二氢-1,2,4-三唑并[3,4-a]异喹啉进行烷基化反应,得到了季铵2-R-5,6-二氢-1,2,4-三唑并[3,4-a]异喹啉盐。在此过程中,有可能形成与钯(II)、吡啶以及2-、3-和4-甲基吡啶的卡宾PEPPSI络合物。
