The New Approach of Expansion Baldwin-Aibassov’s Rules for Ring-Closing Reaction for d- and f-elements Periodic Table of Elements

Abstract

The authors have studied the effect of a magnetic field on Baldwin’s rules. The authors have proposed a new mechanism that takes into account the effect of the angle and energy endoor exo-cyclization. The authors propose to extend the rule Bouldwin not only for sp-, spand sporbits, but and for d d and f f elements of I-VIII of the Periodic table.
