The invention is a method for the control of undesirable broadleaf weeds and grass weeds. More particularly, the invention relates to a method for controlling undesirable weeds by applying to the foliage thereof or to soil containing seeds of the undesirable weeds, a herbicidally effective amount of a 1H-benzotriazole or 2H-benzotriazole compound.
Csp3–N coupling between aliphaticcarboxylicacids and N-heterocycles via electrochemical decarboxylation is reported. Various N-alkylation products are successfully obtained in moderate to good yields in the presence of CF3SO2Na at a constant current in CH3CN under ambient conditions. With the help of the Co(OAc)2·4H2O catalyst, this electrochemical synthesis exhibits satisfying functional-group tolerance
