Abstract: The inventive subject matter relates to novel synthetic processes which use a multifunctional compound (the “TERMINI compound”) having a masked or protected functional group, wherein the TERMINI compound is capable of quantitatively and irreversibly interrupting a living polymerization or a chain organic reaction. After deprotection or demasking of the functional group of the TERMINI compound, the same living polymerization or organic reaction resumes with 100% efficiency, or a different living polymerization or organic reaction resumes with 100% chemoselectivity, respectively. Once incorporated into a growing molecule, the TERMINI compound generates a branching point upon resumption of the polymerization or reaction.
