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 endo- or exo-cyclization. The authors propose to extend the rule Bouldwin not only for sp3-, sp2- and sp- orbits, but and for d1 - d10 and f1 - f14 elements of I-VIII of the Periodic table.
