Heterocyclic compounds, e.g. alkyl 1-alkyl-3-halomethyl-pyrazole-4-carboxylates, can be manufactured using a hydrazinium-CO2 compound, monosubstituted by an R1 group, to introduce a =N-N(alkyl) group into the heterocycle. R1 is an organic substituent selected from the group consisting of C1 to C12 alkyl ; C3 to C8 cycloalkyl ; C2 to C12 alkenyl ; C2 to C12 alkynyl ; C6 to C8 aryl ; C7 to C19 arylalkyl ; and C7 to C19 alkylaryl ; each of which may be substituted by one or more groups selected from the group consisting of R', X, OR', SR', NR'2, SiR'3, COOR', C(O)R', CN and CONR'2 wherein R' is H or a C1 to C12 group.
杂环化合物,例如烷基1-烷基-3-卤甲基吡唑-4-羧酸酯,可以使用一种被R1基团单取代的联氮-CO2化合物进行制备,将=N-N(烷基)基团引入杂环化合物中。其中,R1是从以下基团中选择的有机取代基:C1至C12烷基;C3至C8环烷基;C2至C12烯基;C2至C12炔基;C6至C8芳基;C7至C19芳基烷基;和C7至C19烷基芳基;每个基团可能被一个或多个来自以下基团的取代基所取代:R'、X、OR'、SR'、NR'2、SiR'3、COOR'、C(O)R'、CN和CONR'2,其中R'是氢或C1至C12基团。
