Correlation
between yield and reduced mass of raw materials in intramolecular C-N, C-C, C-O
coupling reactions and intramolecular/intermolecular Diels-Alder reactions was revealed.
The regression equation was found to be the same as that of intermolecular
reactions; yield = -0.1861<i>M</i><sub>AB</sub>/(<i>n</i><sub>A</sub><i>n</i><sub>B</sub><i>n</i><sub>I</sub>)+100.0, where <i>M</i><sub>AB</sub> is the reduced mass
per mole and <i>n</i><sub>A</sub> and <i>n</i><sub>B</sub> are the total number
of each reaction site in molecular A and molecular B in the reaction system,
and <i>n</i><sub>I</sub> is the number to distinguish whether it is a
intramolecular reaction or intermolecular reaction.
