We have show that 1-hydroxypyrazoles can be prepared easily and regioselectively from the reaction of nitroenamines with ethyl isocyanoacetate. α,β-Unsaturated aci-nitronates are formed in the reaction and are then hydrolysed to give the products by quenching with acid.

In thiylation with arenethiolates 1,2-dinitroalkenes form 1-nitro-2-arylthioalkenes in the more stable Z form, and in the absence of a base they form a mixture of the Z and E isomers.During thiylation with arenethiols 1,4-dinitro-1,3-butadienes only give (E,E)-1-nitro-4-arylthio-1,3-dienes.
