Ed by removal in the Cu(I) dashed lines), is quantitative. Subsequent ring closure by Williamson ether synthesis followed by removal on the Cu(I) template ion with KCN affords the target catenanes in 42 yield. template ion with KCN affords the target catenanes in 42 yield.Within this context, we describe herein a short overview of mechanically linked artificial two.

Rotaxane 1 was developed to field. a field, but rather a short account with illustrative examples of crucial advances in the have cationic Au(III)porphyrinate group (AuP) as to quite a few fantastic functions that have been For substantial critiques, we direct the reader the electron acceptor, which was covalently attached toin the literature [1,24,31,36,568]. whilst the two Zn(II)porphyrinate stoppers published the ring element with the rotaxane, (to prevent dissociation in the rotaxane upon removal from the Cu(I) template ion) were the electron donors. The synthesis of rotaxane 1 was accomplished from an adaptation of your 2.
