Synthetic approaches to self-assembling [n]rotaxanes incorporating Π- electron deficient bipyridinium-based dumbbell-shaped components and Π- electron rich hydroquinone-based macrocycles have been developed. In particular, the so-called slippage methodolo

The exploitation of size-complementarity between the macrocyclic component and the stoppers of the cumbbell component of a rotaxane, together with stabilising noncovalent bonding interactions that create a thermodynamic trap, have permitted the development of an alternative method, which can be termed slippage, for the syntheses of rotaxanes in good yields.

Five triarylcarbinols (8, three new compounds) were synthesized.Using carbanion chemistry the triarylmethanes (13, five new compounds) made by formic acid reduction of 8 were converted to the ω,ω,ω-triarylalkanols (15, three new compounds) and thence to the chloro (17) and iodo (18) derivatives (five new compounds).Via carbocation chemistry p-(triarylmethyl)phenols (20, two new compounds) and aniline (21, new compound) were produced.Alkylation of 20 yielded alcohol (22), benzylic bromide (23), and carboxy (25) functionalized derivatives.The alcohol, halide, phenol, aniline, and carboxylic acid functionalized triarylmethane compounds are suitable end blocking groups for rotaxanes and polyrotaxanes.
