摘要
The exception to the rule that Delta(3)-pyrazolines are not stable unless both nitrogen atoms are substituted that has been recently published, Tetrahedron Lett. 55, 2208, (2014), has been proved false. By means of GIAO/B3LYP/6-311++G(d,p) calculations, it has been shown that the product is a pyrazole formed by rearrangement.
