✦ Synopsis

The first syntheses of [l.l.l.l.l]paracyclophane (1) and [l.l.l.l.l.l]paracyclophane (2) are described, featuring a trifluoroacetic acid promoted Friedel-Crafts cycloalkylation as the final step. We wish to report the first syntheses of [l.l.l.l.l]paracyclophane (1> ([15]PCP) and [l.l.l.l.l.l]paracyclophane (2> ([16]PCP). During the course of our work, there was reported' the synthesis of [l.l.l.l]paracyclophane (A), the first example of this class of paracyclophanes.
