A simple method for N-alkylation of 1, 2-diaminoethane with different alcohols in a fixed-bed reactor using cheap CuO-NiO/γ-Al2O 3 as the catalyst has been developed. The present catalytic system was applicable in the N-alkylation of 1, 2-diaminoethane with both primary and secondary alcohols. Mono-N-alkylation of 1, 2-diaminoethane with low-carbon alcohols resulted in high yields; the yields of tetra-N-alkylation of 1, 2-diaminoethane with low-carbon alcohols declined markedly with the increase of the molecular volume of alcohols.

Fungicidal N-substituted ethylendiamino-dithiocarbamates which do not give rise to the formation of ethylenthiourea
-
, (2008/06/13)
There are disclosed new fungicidally active N-substituted ethylendiamino-dithiocarbamates, in particular such dithiocarbamates which are active against Plasmopara viticola infections (B. et C.) Berl. et de Toni (Peronoapora of the vine) and against infections by other fungi that are noxious to useful agricultural cultivations. An important characteristic of the new fungicidally active dithiocarbamates of the invention is that use thereof does not result in the formation of ethylenthiourea.
