WebThe cyclization constant C may be calculated from the observed ratio of the two products at a given concentration [M]. Generally, the decrease in k c with increasing ring size is much greater than the decrease in [M] so that ordinary bifunctional condensation of more than seven atoms does not yield rings in appreciable amount. 6 WebIn organic chemistry, a cycloaddition is a chemical reaction in which "two or more unsaturated molecules (or parts of the same molecule) combine with the formation of a cyclic adduct in which there is a net reduction of the bond multiplicity ". The resulting reaction is a cyclization reaction. WebIn the process of converting from closed to open form and then back to closed form, the C-1→ C-2 bond rotates.
