A well-behaved dynamic library of cyclophane formaldehyde acetals incorporating diphenylmethane units

A new well-behaved dynamic library (DL) based on acetal cyclophanes incorporating diphenylmethane units is described. The effective molarities of the first two members of this library of cyclic oligomers C-2 and C-3 have been obtained from concentration profiles. Amplification of the dimer in the presence of a silver template, and cross-equilibration experiments are also reported.
