Cyclic macromolecules, or ring polymers, have been synthesized by one of three fundamental approaches (1) backbiting of linear precursors (Jones etal, 1974 Wright and Beevers, 1986 Ruddick et al, 1999 Kricheldorf, 2003 Boston and Beckham, 2010a), (2) ring expansion by bond insertion (Bielawski et al, 2002 Shea et al, 1998 Kricheldorf et al, 1998 Kricheldorf et al, 2002 Bielawski et al, 2003), or (3) end-to-end coupling of difunctional linear precursors in dilute solution (Geiser and Hocker, 1980 Roovers and Toporowski, 1983
