Herein we describe a fullerene rotaxane, in which shuttling between two well-defined and distant co-conformations is both induced and monitored by the C60 stopper.

behaviour of a series of rotaxanes containing a fulleropyrrolidine stopper and two ferrocene moieties on the macrocycle is reported. Remarkably, the presence of large and bulky ferrocene groups does not interfere either in the synthesis or in the translocation of the macrocycle induced by π-π interactions between the macrocycle and the fullerene. The synthetic routes developed can also be applied to the

Thiolcarbonates represented by the formula, ##SPC1## Wherein R.sub.1 and R.sub.2 are individually a hydrogen atom or a methyl group, and R.sub.3 is a straight chain or branched chain saturated or unsaturated alkyl group having 1 to 5 carbon atoms or is a benzyl or benzhydryl group which may be nuclear substituted, are quite useful for protecting the amino or imino groups of amines, hydrazines, amino acids and peptides with groups of the formula ##EQU1## The thiolcarbonates can be easily produced by reacting an alkali metal salt of 2-mercaptopyrimidine with phosgene, and reacting the resulting thiolchloroformate with an alcohol (R.sub.3 OH), or by reacting a 2-mercaptopyrimidine with a halocarbonic acid ester.
