Abstract

This is an exploratory study to determine the cyclization preference in the formation of the pyrazoline product of the reaction between the compound 4-phenyl-1-(1,3-dithiolan-2-ethenyl)-3-buten-2-one and hydrazine. , towards the position neighboring the aromatic ring or to the position neighboring the dithiolan heterocycle.

To determine if the electronic density is decreased on positions 1 and 2 of the compound chain, aromatic ring substrates with electron-attracting groups were used, these being: bromine in ortho position and nitro in meta and para positions, all of them deactivating the electron cloud pi(n). By decreasing the electron density, it was expected to obtain a greater amount of product.
